Use local codes as applicable. Use a minimum wire gauge of 18 AWG. Use shielded cable to minimize equipment malfunctions from electrical noise. A hand operated supply disconnect device must be installed in the final application. The primary disconnect device must meet EN requirements. Inductive coils on relay, contactors, solenoids that are on the same AC power line or housed in the same enclosure should be suppressed with an RC network across the coil. For the best results, use resistance (r) values of 50 ohms and capacitance (c) values of 0.1 microfarads. Install an AC line filter or isolation transformer to reduce excessive EMI noise, such as line notches or spikes, on the AC power line. DANGER Hazardous voltages. Can cause severe injury, death or damage to the equipment. See The National Electrical Code (NEC,) Article 430 published by the National Fire Protection Association, or The Canadian Electrical Code (CEC). CAUTION: The ML-Trim is shipped from the factory nonisolated with J4 and J5 jumpers.

You must remove the J4 and J5 jumpers before you connect the External Power supply or you can damage the equipment. Use the Auxiliary Power Output (J4 pins 1, 2) to supply power to non-isolated operations. Fuse L1 and L2 for 230VAC applications. Use 1 Amp 250V normal blow fuses. This can cause severe injury, death or equipment damage. As a momentary input, Run is internally latched and does not need to be maintained by an operator device. RUN 6 8 J5 Figure 2-8 Run 2-9 Jog (J5 pins 7, 8) Jog is a maintained input. As a maintained input, Jog is only active when the operator device is closed. As a momentary input, F-Stop is internally latched and does not need to be maintained by an operator device. Speed Command Out (J2 pins 1, 2) Speed Command Out is an isolated analog output signal that is sent to the motor drive to control the speed of the motor. Wire the Speed Command Out into the Speed Signal Input of the drive. If the motor drive has a potentiometer speed control, remove the potentiometer connections and wire the Speed Command Output to the potentiometer wiper input. See Figure 2-15. Refer to Operations: Logic Control, Logic Output, page 3-37 for details. NOTE: This is an open-collector relay driver. Alarm Format (CP-10) determines which alarm conditions will activate the Alarm output, using the values that are entered in Low Alarm (CP-12), High Alarm (CP-13), Ramped Error (CP-14) and Scaled Error (CP-15). Use an external DC power supply to power the relays. If this output is used, it will nullify optical isolation. See Operations: Serial Communications, page 3-49 for information on using Serial Communications. The ML-Trim is designed to use with an isolated RS232 to RS485 converter. Figure 2-16 illustrates a multidrop installation of the Serial Communications link and Figure 2-17 illustrates the Serial Communications connections. Refer to EIA Standard RS485A, for more information. Calibration is accomplished in two steps.

The first step is to set up the motor drive. The maximum operating speed is the same speed that you will enter in Max RPM Feedback (CP-34) to scale for the Master mode of operation (Refer to Operation: Control Parameters. Master Mode, page 3-9). Check the speed (RPMs) by pressing the “Tach” key. You can also use the keypad to change the value of a Control Parameter. It also has numeric keys and two dedicated keys: Setpoint and Tach. The LED display is the above the keys. Figure 3-1 displays the location of the keys and LED display on the keypad. Table 3-1 demonstrates basic keypad entry. The keypad functions as follows: Code Select Key Press this key prior to entering a Parameter Code (either a Control Parameter or a Monitor Parameter). Numeric Keys Use the numeric keys to enter a Parameter Code for either a Control Parameter (CP) or a Monitor Parameter (MP) or to enter a value for a Control Parameter. Use the Enter key after each entry. Use the Clear key to delete your entry. Dedicated Keys The Setpoint key and the Tach key are shortcut keys. The Setpoint key accesses the active setpoint variable directly and the Tach key accesses the tach variable directly (rather than manually entering the Code Parameter). Each time you press the scroll up key, the active setpoint will increase by one increment. Each time you press the scroll down key, the active setpoint value will decrease by one increment. It will also automatically scroll through the increments or decrements if you hold the key down. LED Display The two digit Parameter Code is displayed on the left LED Display. The Parameter Code's value is displayed on the right LED display. This value can be up to four digits. 3-3 Table 3-1 Basic Keypad Entry To Enter a Parameter Code: Press “Code Select”. Enter a Parameter Code (For a Control Parameter or Monitor Parameter). Press “Enter” (within 15 seconds). The Parameter Code and it's current value are displayed on the LED display.

The Parameter Code decimal point is illuminated. To Enter a Parameter Value: Follow the steps to enter a Parameter Code. Enter a new value (Use the numeric keys). The Parameter Code decimal point turns “Off”. (For Control Parameters only - Monitor Parameters can not be changed manually) To Use the Tach Key: Press “Tach’. The scaled Engineering Unit Feedback is displayed. To Use the Setpoint Key: Press “Setpoint”. The active setpoint and its value are displayed. Press the “Down” scroll key to decrease the active setpoint value. When the keypad is locked, then “LOC” is displayed: Code Locked When the Keypad is unlocked, then “ULOC” is displayed: Code Unlocked To lock out the keypad, enter a numerical “password” between “1” and “9999” in Keypad Lockout (CP-98), then press the “enter” key. This numerical password will flash briefly on the screen, then the screen will display “LOC”. To unlock the keypad, enter the same numerical password in Keypad Lockout (CP-98). The number will flash briefly on the screen and then the screen will display “ULOC”. Control Parameters and Monitor Parameters may be monitored during lockout, however, Control Parameters can not be changed during lockout. CAUTION: Make certain that you record your password in the space provided on page 3-6, as your password becomes transparent once you have entered it. If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3. 3-5 Record your numeric Keypad Lockout password here: Please read the “CAUTION” statement on Page 3-5 3-6 CONTROL PARAMETERS Parameters are divided into two classifications; Control Parameters (CP) and Monitor Parameters (MP). The numbered code that represents the Parameter is the Parameter Code. The operational data is the Parameter's value. Monitor Parameters are explained in Operation: Monitor Parameters, page 3-39. The majority of these default settings are suitable for most applications and do not require modification.

The mode of operation that you use is determined by your systems operational requirements. The following subsections demonstrate how to enter Control Parameters for the Direct mode, Master (stand-alone) mode or the Follower mode of operation. Direct mode is an open-loop mode of operation. The Direct mode is used in conjunction with the Run and Stop controls. To enable or disable Direct mode, use the Direct Enable (CP-61). The factory default Control Parameters for the Direct mode are found in Table 3-2. To modify the default parameters, refer to Table 3-3. If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3. Table 3-2 Default Direct Mode Control Parameters CP Parameter Name Parameter Value CP-06 Direct Setpoint 0 CP-61 Direct Enable 0 Table 3-3 Entering Direct Mode Control Parameters 3-8 CP Parameter Name Parameter Value CP-06 Direct Setpoint Enter the percentage of the calibrated full scale Speed Command output at which you want your system to operate. CP-61 Direct Enable Enter “1” to enable the Direct Mode. Enter “0” to disable the Direct Mode. Master Mode The Master, or stand-alone mode of operation, is a single motor operation. The Master Engineering Units at which you want the system to operate, are entered into the two available Master Setpoints (CP-01 and CP-02). Scaling is a convenient method for translating the relationship of the motor RPMs into Master Engineering Units. This number is identical to the maximum operating speed that you set in step 7 of the calibration procedure on page 2-20. PPR Feedback (CP-31) The number of gear teeth or number of encoder lines on the feedback sensor per one revolution (pulses per revolution). Master Engineering Units (CP-20) The actual value of the Master Engineering Units if the system were to operate at the maximum RPMs that you entered in Max RPM Feedback (CP-34). The factory default Control Parameters for Scaling are found in Table 3-4.

To modify the default parameters, refer to Table 3-5. If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3. Information on setpoint entry follows Table 3-5. 3-9 Table 3-4 Default Master Scaling Control Parameters CP Parameter Name CP-34 Max RPM Feedback CP-31 PPR Feedback CP-20 Master Engineering Units Parameter Value 2000 60 2000 Table 3-5 Entering Master Scaling Control Parameters CP Parameter Name Parameter Value CP-34 Max RPM Feedback Enter the maximum desired RPMs, measured at the sensor shaft. CP-31 PPR Feedback Enter the number of gear teeth or encoder lines on the sensor per one revolution (pulses per revolution). CP-20 Master Engineering Units Enter the Master Engineering Units value if the system were to operate at the maximum desired RPMs entered in CP-34. Now that your scaling has been established, you can enter a value for Master Setpoints 1 and 2. The value that you enter for a setpoint is the Engineering Units (E.U.s) that you want to operate your system at. The factory default Control Parameters for Master Setpoint 1 and 2 are set at “0”. To modify these default parameters, refer to Table 3-6. You can toggle between the two setpoints, if you have wired the Setpoint Select accordingly. Setpoint Select (located at J5 pins 13, 14), determines which of the two setpoints is active (refer to Setpoint Select on page 2-12). If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3. 3 - 10 Table 3-6 Entering Master Setpoint Control Parameters CP Parameter Name Parameter Value CP-01 Master Setpoint 1 Enter the Master Engineering Units value that you want your system to operate at when Setpoint 1 is active. CP-02 Master Setpoint 2 Enter the Master Engineering Units value that you want your system to operate at when Setpoint 2 is active. The motor shaft is equipped with a 30 tooth Ring kit. The Master Engineering Units are gallons per minute.

Master Setpoint 1 will be setup to pump 10 gallons per minute when it is the active setpoint. Master Setpoint 2 will be setup to pump 5 gallons per minute when it is the active setpoint. The following section demonstrates how to enter Control Parameters for the Follower mode of operation. 3 - 12 Follower Mode The Follower mode of operation is the most frequently used mode of operation. The Follower Engineering Units that you want the system to operate at are entered into the two available Follower Setpoints (CP-03 and CP-04). Scaling is a convenient method for translating the relationship of the Lead and Follower motor RPMs into Follower Engineering Units. Max RPM Feedback (CP-34) Measured at the sensor shaft, this number is the maximum RPMs at which you want the follower to operate when the Lead is operating at its maximum RPMs. This number is identical to the maximum operating speed that you set in step 7 of the calibration procedure on page 2-20. PPR Lead (CP-30) The number of gear teeth or number of encoder lines on the Lead sensor per revolution (pulses per revolution). PPR Feedback (CP-31) The number of gear teeth or number of encoder lines on the Follower feedback sensor per revolution. Follower Engineering Units (CP-21) Enter a number that will represent the setpoint Engineering Units when the Lead and Follower are operating at their maximum RPMs. This number is usually either the ratio of Max RPM Feedback (CP-34) to Max RPM Lead (CP-33) or the ratio of Follower to Lead Engineering Units at maximum desired RPM. When this number is also entered as a setpoint (CP-03 or CP-04), the Follower will operate at maximum desired RPM when the Lead is at maximum desired RPM. 3 - 13 The factory default Control Parameters for Scaling are found on Table 3-8. To modify these default parameters, refer to Table 3-9. If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3.

Table 3-8 Default Follower Scaling Control Parameters CP Parameter Name Parameter Value CP-33 Max RPM Lead 2000 CP-34 Max RPM Feedback 2000 CP-30 PPR Lead 60 CP-31 PPR Feedback 60 CP-21 Follower Engineering Units 1.000 Table 3-9 Entering Follower Scaling Control Parameters 3 - 14 CP Parameter Name Parameter Value CP-33 Max RPM Lead. Enter the maximum operating RPM of the Lead motor, measured at the Lead sensor shaft (pulses per revolution). CP-34 Max RPM Feedback Enter the maximum desired RPM of the Follower motor, measured at the Follower feedback sensor shaft. CP-33 PPR Lead Enter the number of gear teeth or encoder lines on the Lead sensor. CP-31 PPR Feedback Enter the number of gear teeth or encoder lines on the Follower feedback sensor. CP-21 Follower Engineering Units Enter the Engineering Units value if the Lead (CP-33) is operating at maximum RPM and the Follower (CP-34) is operating at maximum RPM. With your scaling established, you can enter values for Follower Setpoints 1 and 2 (CP-03, CP-04). The factory preset, default Follower Setpoints 1 and 2 (CP-03 and CP-04) are set at “0”. To modify these default parameters, refer to Table 3-10. Table 3-10 Entering Follower Setpoint Control Parameters CP Parameter Name Parameter Value CP-03 Follower Setpoint 1 Divide the Follower E.U. that you want, by the Lead E.U. that the Lead is operating at, and enter that value. CP-04 Follower Setpoint 2 Divide the Follower E.U. that you want, by the Lead E.U. that the Lead is operating at, and enter that value. The Lead sensor shaft is equipped with a 60 tooth Ring kit. The Follower sensor shaft is equipped with a 30 tooth Ring kit. Multiplied by 100 (%) Equals 50 Follower Setpoint 1 (CP-03) value. Multiplied by 100(%) Equals 70 3 - 20 Follower Setpoint 2 (CP-04) value. The Inverse Master Mode has an inverted setpoint. If you increase the value of the setpoint (CP-01 or CP-02), then the motor speed will decrease.

Inverse Mode setpoints generally use engineering units of time. With the Inverse Scaling (CP-62) set to “2”, enter values in the Master Setpoints (CP-01 and CP-02) that represent the E.U. at which you want the system to operate. The higher the setpoint value; the slower the motor speed. Inversely, the lower the setpoint value; the higher the motor speed. These default settings are not suitable for Inverse applications and require modification. The factory default Control Parameters for the standard Master Mode are found in Table 3-13. To modify these default parameters, refer to Table 3-14. If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3. Table 3-13 Default Inverse Master Control Parameters CP Parameter Name Parameter Value CP-62 Inverse Scaling 1 (Standard Scaling) CP-20 Master E.U. 2000 Table 3-14 Entering Inverse Master Control Parameters 3 - 22 CP Parameter Name Parameter Value CP-62 Inverse Scaling Enter “2” for Inverse Scaling. CP-20 Master E.U. Enter the minimum Master Engineering Units value if the system were to operate at the maximum RPMs entered in (CP-34). Inverse Master Mode Example The Inverse Master Mode Example demonstrates how scaling and setpoint Control Parameters are entered for a typical Inverse Master mode of operation: It takes 10 seconds to move a product through a heat treat oven when the conveyor motor is running at 1500 RPM. The conveyor motor shaft is equipped with a 60 tooth ring kit. Set Master Setpoint 1 (CP-01) so that the product is in the oven for 20 seconds. Set Master Setpoint 2 (CP-02) so that the product is in the oven for 15 seconds. The following section demonstrates how to enter Control Parameters for the Inverse Follower mode of operation. 3 - 23 Inverse Follower Mode The Inverse Follower Mode is a variation of the Follower Mode. The Inverse Follower Mode has an inverted setpoint.

If you increase the value of the setpoint (CP-03 or CP-04), then the ratio of Follower speed to Lead speed will decrease. With the Inverse Scaling (CP-62) set to “2”, enter values in the Follower Setpoints (CP-03 and CP-04) that represent the E.U. at which you want the system to operate. The higher the setpoint value; the lower the Follower to Lead ratio speed. The factory default Control Parameters for the standard Follower Mode are found in Table 3-16. To modify these default parameters, refer to Table 3-17. If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3. Table 3-16 Default Inverse Follower Control Parameters CP Parameter Name Parameter Value CP-62 Inverse Scaling 1 (Standard Scaling) CP-21 Follower E.U. 1.000 Table 3-17 Entering Inverse Follower Control Parameters 3 - 24 CP Parameter Name Parameter Value CP-62 Inverse Scaling Enter “2” for Inverse Scaling. CP-21 Follower E.U. Enter the minimum Engineering Units if the system were to operate at the Max RPM Lead (CP-33) and the Max RPM Feedback (CP-34). Inverse Follower Mode Example The Inverse Follower Mode Example demonstrates how the scaling and setpoint Control Parameters are entered for a typical Inverse Follower mode of operation: In a wire machine twisiting application, the Follower twists the wire as the Lead pulls the wire. When the Follower is at the maximum revolutions per minute of 1800 RPM and the Lead is at the maximum revolutions per minute of 2000 RPM, then the twist length (lay) is at its minimum of 2.0 inches. The Follower motor uses a 1200 PPR encoder and the Lead motor shaft is equipped with a 60 tooth ring kit. These parameters apply to both the Master and Follower modes of operation. Generally, these default settings are suitable for most applications and do not require modification. The factory default Control Parameters for Timing are found in Table 3-19. To modify these default parameters, refer to Table 3-20.

The tuning Control Parameters are identical for both the Master and the Follower modes of operations. Tuning is discussed in the following section. 3 - 26 Tuning If your system is unstable, or the speed error is unacceptable, tuning stabilizes speed error differences between the setpoint and feedback. You can achieve a stable system using conservative tuning Control Parameter values, however the speed error may be unacceptable. On the other hand, aggressive tuning Control Parameter values may cause the system to become unstable. The goal is to reduce the speed error to the level that you want, yet maintain the system's stability. To achieve an acceptable level of speed error, adjust the Gain (CP-65) until the system stabilizes. In systems that require greater accuracy, it may be necessary to adjust the Integral (CP-66) to reduce any remaining speed error. In systems with low inertia, the speed error will be reduced more quickly if you enter low values in CP-66. An entry that is too low, however, can create instability or overshoot the setpoint before reaching the correct value. Generally, use larger entries for CP-66 on systems with a large inertia. Sometimes performance can be improved in systems with a large inertia by lowering the Derivative (CP-67). These default settings are suitable for most applications and do not require modification. The factory preset, default tuning Control Parameters are found in Table 3-21. To modify these default parameters, refer to Table 3-22. Reduced values will increase Gain. To verify the stability of the speed changes, you can access Tach through either the Tach key or the Monitor Parameter for Tach (MP-40). CP-66 Integral While switching between the high and low setpoints, decrease the Integral's default value of “2000” until the speed error is reduced within an acceptable time frame. To verify the stability of the speed changes, you can access Tach through either the tach key or the Monitor Parameter for Tach (MP-40).

CP-67 Derivative The Derivative should not be adjusted in most systems. However, sometimes in the larger inertia systems you can improve performance by lowering the Derivative term to the point of instability and then increasing it incrementally until the system stabilizes. After the Control Parameters for Tuning have been entered, you can enter the Control Parameters for the Alarms for either the Master or the Follower mode. Alarms are discussed in the following section. 3 - 28 Alarms The Control Parameters for Alarms are identical for both the Master and the Follower modes of operations. The alarm output can be wired to activate a warning light, a warning sound, or to shut down the system under specified conditions. This allows you to either operate your system unfettered by the alarm or design your own alarm conditions that are unique to your system. The factory default Control Parameters for the Alarms are found in Table 3-23. To modify these default parameters, refer to Table 3-24. Alarm Format (CP-10) determines which alarm conditions will activate the Alarm output, using the values that are entered in Low Alarm (CP-12), High Alarm (CP-13), Ramped Error Alarm (CP-14) and Scaled Error Alarm (CP-15). CP-12 Low Alarm CP-13 High Alarm Enter the RPMs at or below which you want the Alarm output to activate. Enter the RPMs at or above which you want the Alarm output to activate. CP-14 Ramped Error Alarm Enter the RPM Deviation between the Ramped Reference and the feedback that will activate the Alarm output. CP-15 Scaled Error Alarm Enter the RPM Deviation between the Scaled Reference and the feedback that will activate the Alarm output. Jog Jog increases the RPMs at the acceleration rate that you specified in Acceleration Time (CP-16) until the Jog Setpoint (CP-05) is achieved. When Jog is terminated, there is no Deceleration Time (CP-17); the drive comes to an immediate stop. The factory default Control Parameter for Jog is found in Table 3-25.

To modify this default parameter, refer to Table 3-26. If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3. Table 3-25 Default Jog Control Parameters CP Parameter Name CP-05 Jog Setpoint Parameter Value 50 Table 3-26 Entering Jog Control Parameters CP Parameter Name Parameter Value CP-05 Jog Setpoint Enter the RPM at which you want your system to operate when it is in Jog. The motor drive is activated by the Drive Enable digital output. The sections that follow demonstrate how to use the digital inputs and the Drive Enable output. Caution Do not use the AC line power to start or stop the system. Run ramps to the scaled setpoint speed, using the Acceleration Time (CP-16). Jog ramps to the Jog Setpoint (CP-05), using the Acceleration Time (CP-16). Unlike the other inputs, Jog is not latched and must be sustained to remain active. RUN 6 RUN 7 JOG 8 COMMON 9 R-STOP 10 F-STOP 11 COMMON JOG R-STOP F-STOP J5 Maintain Closed 3 - 36 Logic Output Drive Enable activates the motor drive based on the Ramped Reference (MP-46) and the feedback. Drive Enable Logic (CP-74) determines which conditions of the Ramped Reference (MP-46) and feedback will control the Drive Enable output. The factory defaults for Drive Enable Logic (CP-74) is found in Table 3-27. To modify this default parameter, refer to Table 3-28. If you are uncertain how to enter a Control Parameter, review the Operations: Keypad section, page 3-3. Table 3-27 Default Drive Enable Logic Control Parameter CP Parameter Name CP-74 Drive Enable Logic Parameter Value 0 Table 3-28 Entering Drive Enable Logic Control Parameter CP Parameter Name CP-74 Drive Enable Logic Parameter Value Enter “0” in CP-74 to deactivate the Drive Enable output (output high) when the Ramped Reference is zero, and activate the Drive Enable output (output low) when the Ramped Reference is not zero.http://www.cseforyou.it/images/3rz-fe-engine-manual.pdf
