10.0 CONTROL WIRING 10.1 CONTROL WIRING VS. POWER WIRING External control wiring MUST be run in a separate conduit away from all other input and output power wiring. If control wiring is not kept separate from power wiring, electrical noise may be generated on the control wiring that will cause erratic drive behavior. Use twisted wires or shielded cable grounded at the drive chassis ONLY. Recommended control wire is Belden 8760 (2-wire) or 8770 (3-wire), or equivalent.
10.6 SPEED REFERENCE SELECTION If an analog speed reference input is used to control the drive speed, terminal TB-13A, 13B, or 13E (Parameter 10, 11, or 12) may be programmed as the input select for the desired analog input signal. When that TB-13 terminal is then closed to TB-11, the drive will follow the selected analog speed reference input.
NOTE If TB-13A, TB-13B, and TB-13E are all programmed to select speed references, and two or three of the terminals are closed to TB-11, the higher terminal has priority and will override the others. For example, if TB-13A is programmed to select 0-10VDC, and TB-13E is programmed to select PRESET SPEED #3, closing both terminals to TB-11 will cause the drive to respond to PRESET SPEED #3, because TB-13E overrides TB-13A. The exception to this is the MOP function, which requires the use of TB-13B and TB-13E.
11.0 SCL/SCM CONTROL WIRING DIAGRAMS 11.1 SCL/SCM TERMINAL STRIP Shown below is the control terminal strip, along with a brief description of the function of each terminal. The following wiring diagram examples provide a quick reference to wire the drive for the most common configurations.

12.0 INITIAL POWER UP AND MOTOR ROTATION DANGER! Hazard of electrical shock! Wait three minutes after disconnecting incoming power before servicing drive. Capacitors retain charge after power is removed. STOP! • DO NOT connect incoming AC power to output terminals U, V, and W or terminals B+, B-! Severe damage to the drive will result. Do not continuously cycle input power to the drive more than once every two minutes. Damage to the drive will result.
Follow the procedure below to check the motor rotation. This procedure assumes that the drive has been powered up for the first time, and that none of the parameters have been changed. 1. Use the M button to decrease the speed setpoint to 00.0 Hz. The left decimal point will illuminate as the speed setpoint is decreased. If the M button is held down, the speed setpoint will decrease by tenths of Hz until the next whole Hz is reached, and then it will decrease by one Hz increments.
13.0 PROGRAMMING THE SCL/SCM DRIVE The drive may be programmed by one of two methods: using the three buttons and 3-digit LED display on the front of the drive, or programming the Electronic Programming Module (EPM) using the optional EPM Programmer. This section describes programming the drive using the buttons and display, which are shown below: BUTTONS DISPLAY Mode To enter the PROGRAM mode to access the parameters, press the Mode button.
NOTE If the display flashes “Er”, the password was incorrect, and the process to enter the password must be repeated. Use the L and M buttons to scroll to the desired parameter number. In the example below, Parameter 19 is being displayed, which is the ACCELERATION TIME of the drive: Use L and M to scroll to the desired parameter number (the example is Parameter 19 - ACCELERATION TIME) Once the desired parameter number is found, press the Mode button to display the present parameter setting.
13.1 SETTING VALUES IN TENTHS OF UNITS ABOVE 100 Parameter settings and the keypad speed command can always be adjusted in tenths of unit increments from 0.0 to 99.9. Above 100 however, values can be set in whole units or tenths of units, depending on the setting of Parameter 16 - UNITS EDITING. If Parameter 16 - UNITS EDITING is set to WHOLE UNITS (02), parameter values and the keypad speed command can only be adjusted by whole unit increments above 100.
13.2 ELECTRONIC PROGRAMMING MODULE (EPM) Every SCL/SCM Series drive has an Electronic Programming Module (EPM) installed on the main control board. The EPM stores the user’s parameter settings and special OEM default settings (if programmed). The EPM is removable, allowing it to be installed in another drive for quick set-up. For example, if a drive is being replaced with a new one, the EPM can be taken out of the first drive and installed in the new drive.

15.0 DESCRIPTION OF PARAMETERS P01 LINE VOLTAGE SELECTION This calibrates the drive for the actual applied input voltage. Set this parameter to HIGH (01) for 120, 220-240, and 460-480 Vac input, or LOW (02) for 200-208 and 380-415 Vac input. NOTE If this parameter is changed while the drive is running, the new value will not take effect until the drive is stopped. P02 CARRIER FREQUENCY This sets the switching rate of the output IGBT’s.
03 START WITH DC BRAKE: When a START command is given, the drive will apply DC BRAKE VOLTAGE (Parameter 22) for the duration of DC BRAKE TIME (Parameter 21) prior to starting the motor to ensure that the motor is not turning. 04 AUTO RESTART WITH DC BRAKING: Upon a START command, after a fault, or upon application of power, the drive will apply DC BRAKE VOLTAGE (Parameter 22) for the duration of DC BRAKE TIME (Parameter 21) prior to starting (or restarting) the motor.
P05 STANDARD SPEED SOURCE This selects the speed reference source when the drive is in STANDARD speed mode. The following speed references can be selected: 01 KEYPAD: Use the L and M buttons to scroll to the desired speed. 02 PRESET SPEED #1: The drive will operate at the frequency set into Parameter 31. 03 0-10 VDC: The drive will respond to a 0-10 VDC signal wired to TB-5 (+) and TB-2 (-). 04 4-20 mA: The drive will respond to a 4-20 mA signal wired to TB-25 (+) and TB-2 (-).
P10 TB-13A FUNCTION SELECT This selects the function of terminal TB-13A. Closing TB-13A to TB-11 (or opening in the case of settings 08 and 10) activates the selected function. The following functions can be selected: 01 NONE: Disables the TB-13A function. 02 0-10 VDC: Selects a 0-10 VDC signal (at TB-5) as the AUTO speed reference input. 03 4-20 mA: Selects a 4-20 mA signal (at TB-25) as the AUTO speed reference input. 04 PRESET SPEED #1: Selects PRESET SPEED #1 as the speed reference.
06 START FORWARD: Sets up the drive for a 3-wire start/stop circuit. Momentarily close TB-13B to TB-11 to start the drive, and momentarily open TB-1 to TB-11 to stop. 07 JOG FORWARD: Close TB-13B to TB-11 to JOG in the forward direction. The drive will run at PRESET SPEED #2 (Parameter 32) when in JOG mode. 08 JOG REVERSE: Close TB-13B to TB-11 to JOG in the reverse direction. The drive will run at PRESET SPEED #2 (Parameter 32) when in JOG mode.
When used as an output, it can provide the drive's status for monitoring. If the Remote Keypad option is being used, this parameter must be set to REMOTE KEYPAD (21). The following input functions can be selected: 01 NONE: Disables the TB-13E function. 02 0-10 VDC: Selects a 0-10 VDC signal (at TB-5) as the AUTO speed reference input. 03 4-20 mA: Selects a 4-20 mA signal (at TB-25) as the AUTO speed reference input. 04 PRESET SPEED #3: Selects PRESET SPEED #3 as the speed reference.
17 CURRENT LIMIT: Closes if the output current exceeds the CURRENT LIMIT setting. Opens if the output current is equal to or less than CURRENT LIMIT (see Parameter 25). 18 AUTOMATIC SPEED MODE: Closes if an AUTOMATIC (terminal strip) speed reference is active. Opens if a STANDARD (Parameter 5) speed reference is active. 19 REVERSE: Closes when reverse rotation is active. Opens when forward rotation is active (see Parameter 17 - ROTATION DIRECTION).
P19 ACCELERATION TIME This sets the acceleration rate for all of the speed reference sources (keypad, speed pot, jog, MOP, and preset speeds). This setting is the time to accelerate from 0 Hz to the BASE FREQUENCY (Parameter 27). P20 DECELERATION TIME This sets the deceleration rate for all of the speed reference sources (keypad, speed pot, jog, MOP, and preset speeds). This setting is the time to decelerate from BASE FREQUENCY to 0 Hz.
NOTE If this parameter is changed while the drive is running, the new value will not take effect until the drive is stopped. P25 CURRENT LIMIT This sets the maximum allowable output current of the drive. The maximum setting is either 180% or 150%, depending on whether LINE VOLTAGE SELECTION (Parameter 01) is set to HIGH or LOW. If the load demands more current than the CURRENT LIMIT setting, the drive will reduce the output frequency in an attempt to reduce the output current.
P29 ACCELERATION BOOST ACCELERATION BOOST helps accelerate high-inertia loads. During acceleration, the output voltage is increased to increase motor torque. Once the motor reaches the new speed setpoint, the boost is turned off and the output voltage returns to the normal value. P30 SLIP COMPENSATION SLIP COMPENSATION is used to counteract changes in motor speed (slip) caused by changes in load.
Example: The critical frequency is 23 Hz, and it is desired to skip a frequency range of 3 Hz above and below the critical frequency (therefore the skip range is 20 to 26 Hz). PRESET SPEED #6 or #7 would be set to 20 Hz, and the SKIP BANDWIDTH would be set to 6 Hz.
P45 SPEED AT MIN SIGNAL This sets the speed at which the drive will run when it receives the minimum speed reference signal (0 VDC or 4 mA). This is used in conjunction with SPEED AT MAX SIGNAL (Parameter 46) to define the speed range of the drive when following an analog speed reference signal. P46 SPEED AT MAX SIGNAL This sets the speed at which the drive will run when it receives the maximum speed reference signal (10 VDC or 20 mA).
06 TRANSLATE: If an EPM from a drive with a previous (but compatible) parameter version is installed in a new drive, the new drive will function like the previous version drive, but none of the parameter settings can be changed ("cE" will be displayed if this is attempted).
P54 MOTOR LOAD This displays the motor load in percent of the drive’s output current rating. P55 0-10 VDC INPUT This displays the level of the 0-10 VDC input signal at TB-5. A reading of 100% indicates a 10 VDC input at TB-5. P56 4-20 mA INPUT This displays the level of the 4-20 mA input signal at TB-25. A reading of 20% indicates a 4 mA input at TB-25, and a reading of 100% indicates a 20 mA input at TB-25.
16.0 TROUBLESHOOTING To aid in troubleshooting, Parameters 50 through 60 can be accessed without entering the PASSWORD. Simply press the Mode button twice to “skip” over the PASSWORD prompt, and “P50” will be displayed to indicate that the parameter menu has been entered and Parameter 50 (FAULT HISTORY) can be viewed. The L and M buttons can then be used to scroll from Parameter 50 to Parameter 60. Once the desired parameter is found, press the Mode button to view its “contents”.
The table below lists the fault conditions that will cause the drive to shut down, as well as some possible causes. Please contact the factory for more information on troubleshooting faults. FAULT MESSAGES FAULT DESCRIPTION & POSSIBLE CAUSES AF High Temp. Fault: Ambient temperature is too high; Cooling fan has failed (if equipped). CF Control Fault: A blank EPM, or an EPM with corrupted data has been installed. Perform a factory reset using Parameter 48 - PROGRAM SELECTION.
17.0 SCL/SCM DISPLAY MESSAGES The following describes the various displays and messages that can appear on the SCL/SCM drive. 17.1 SPEED DISPLAY If the drive is in a STOP state (indicated by "- - -" on the display), and the commanded speed is changed, the display will show the commanded speed, and the upper left decimal point will turn on solid. About five seconds after a change is made, the display will begin to alternate between the commanded speed value and the "- - -" display.
SPEED SOURCE DISPLAYS DISPLAY DESCRIPTION CP CONTROL PAD: Speed is set using the L and M buttons on the front of the drive. EI EXTERNAL CURRENT: Speed is controlled by a 4-20 mA signal wired to TB-25 and TB-2 EU EXTERNAL VOLTAGE: Speed is controlled by a 0-10 VDC signal wired to TB-5 and TB-2. JG JOG: The drive is in Jog mode, and the speed is set by Preset Speed #2 (Parameter 32). OP MOP (Motor Operated Pot): Contacts wired to TB-13B and TB-13E are used to increase and decrease the drive speed.
