SELECT SWITCHES
Select Switch (SW501)
Dip Switch 1: ON - Torque Mode - The drive will control the torque (current) of the motor. This is used
Dip Switch 1: ON -
in tensioning applications.
Dip Switch 1: OFF - Speed Mode - The drive will control the speed (voltage) or the motor. This is used
Dip Switch 1: OFF -
in variable speed applications.
Dip Switch 2: ON - WigWag Mode - The potentiometer or analog signal determines both motor speed
Dip Switch 1: ON - WigWag Mode - and direction. The direction switch will still come into effect.

switch determines the direction. If using a bidirectional
Dip Switch 1: OFF - Pot/Switch Mode -
analog signal (0 to ± 10 VDC), the polarity of the signal
Dip Switch 1: OFF - Pot/Switch Mode -
determines the direction (ie -10 VDC is full speed reverse,
Dip Switch 1: OFF - Pot/Switch Mode -
0 VDC is zero speed, 10 VDC is full speed forward). The direction
Dip Switch 1: OFF - Pot/Switch Mode -
switch will still come into effect even with a bidirectional signal.
Dip Switch 3: ON - Brake Mode - Opening the ENABLE switch will regeneratively brake the motor to
zero speed without applying the decel ramp. At zero speed, the drive
will apply holding torque.
Dip Switch 1: OFF - Enable Mode - Opening the ENABLE switch will coast the motor to a stop. The drive
cannot provide holding torque at zero speed because it's disabled.

LEDs
Power (IL1): Green LED is solid when AC line voltage is applied to the drive, but the drive is disabled. It
flashes whenever AC line voltage is applied to the drive and the drive is enabled.
Status (IL2): Red LED is solid when in current limit or flashes following fault code:
2 Flashes: Undervoltage - Internal DC BUS voltage dropped too low.
3 Flashes: Overvoltage - Internal DC BUS voltage rose too high.
4 Flashes: Current Limit or Short Circuit - The drive is in current limit or has detected a short across the
motor.
5 Flashes: Overtemperature Shut Down - Drive's temperature has reached critical temperature.
6 Flashes: Overtemperature Warning - Drive's temperature is approaching critical temperature.
Maximum motor current is being reduced gradually as the drive's temperature rises.

Decelerate to Minimum or Zero Speed
The switch shown below may be used to decelerate a motor to a minimum speed. Opening the switch
between S3 and the potentiometer decelerates the motor from set speed to a minimum speed
determined by the MIN SPEED trim pot setting. If the MIN SPEED trim pot is set full CCW, the motor
decelerates to zero speed when the switch is opened. The DECEL TIME trim pot setting determines the
rate at which the drive decelerates when travling in the forward direction. By opening the switch, the
motor accelerates to set speed at a rate determined by the ACCEL TIME trim pot setting if accelerating
in the forward direction.

PWM drives are limited in their regnerative capability. The regenerative energy is returned into the
drive's bus capacitor. When this capacitor is full, the drive can no longer regen until the capacitor begins
to empty. During these periods, the motor actually coasts. While the regen/coast periods are frequent
enough that the user may not see the transitions, it does result in a longer deceleration time.
The solution is a brake resistor. When the capacitor is full, the drive will divert the regen energy through
through the resistor. For the regenerative brake resistor, use a 40 watt minimum, high power, wire-
wound resistor. Sizing the regenerative brake resistor depends on load inertia, motor voltage, and
braking time. Use a lower-value, higher-wattage dynamic brake resistor to stop a motor more rapidly.
Brake resistor values must not be less than 40 ohms.
Please note that applications with light regenerative loads may not require the
use of a regenerative brake resistor.
If using a regenerative brake resistor, connect the resistor across terminals W and +BUS.

Calibration
CALIBRATION INSTRUCTIONS ARE ASSUMING THAT THE DRIVE IS SET UP FOR SPEED MODE AND
POT/SWITCH MODE. IF USING TORQUE MODE OR WIGWAG MODE, PLEASE REFER TO THE USER'S
MANUAL.
Zero Adjust (P1 / ZERO ADJ): The ZERO ADJ setting adjusts out any non-linearities in the logic circuit that
might arise from component tolerances. This factory calibrated and should not need any adjustment.
Minimum Speed (P2 / MIN SPEED): The MIN SPEED setting determines the minimum motor speed
when the speed adjust potentiometer is set for minimum speed. It is factory set for zero speed. To
calibrate the MIN SPEED:
1. Set the MIN SPEED trim pot full CCW.
2. Set the speed adjust potentiometer or input voltage or current signal for minimum speed.
3. Adjust the MIN SPEED trim pot until the desired minimum speed is reached or is just at the
3.
threshold of rotation.
Maximum Forward Speed (P3 / MAX FWD SPEED): The MAX FWD SPEED setting determines the
maximum motor speed in the forward direction when the speed adjust potentiometer or input voltage
or current signal is set for maximum speed. It is factory set for maximum motor rated speed. To
calibrate the MAX FWD SPEED:
1. Set the MAX FWD SPEED trim pot full CCW.
2. Set the speed adjust potentiometer or input voltage or current signal for maximum forward
speed.
3. Adjust the MAX FWD SPEED trim pot until the desired maximum forward speed is reached.
Maximum Reverse Speed (P4 / MAX REV SPEED): The MAX REV SPEED setting determines the
maximum motor speed in the reverse direction when the speed adjust potentiometer or input voltage
or current signal is set for maximum speed. It is factory set for maximum motor rated speed. To
calibrate the MAX REV SPEED:
1. Set the MAX REV SPEED trim pot full CCW.
2. Set the speed adjust potentiometer or input voltage or current signal for maximum reverse
speed.
3. Adjust the MAX REV SPEED trim pot until the desired maximum reverse speed is reached.
Check the ZERO ADJ, MIN SPEED, MAX FWD SPEED and MAX REV SPEED adjustments after recalibrating
to verify that the motor runs at the desired minimum and maximum speeds.
Acceleration (P5 / ACCEL TIME): The ACCEL TIME setting determines the time the motor takes to ramp
to a higher speed regardless of direction. To calibrate the ACCEL TIME, turn the ACCEL TIME trim pot
CW to increase the forward acceleration time and CCW to decrease the forward acceleration time.
Deceleration (P6 / DECEL TIME): The DECEL TIME setting determines the time the motor takes to ramp
to a lower speed regardless of direction. To calibrate the DECEL TIME, turn the DECEL TIME trim pot
CW to increase the forward deceleration time and CCW to decrease the forward deceleration time.
Forward Torque (P7 / MOTOR CUR LIM): The MOTOR CUR LIM setting determines the maximum
torque for accelerating and driving the motor in the forward or reverse directions. To calibrate the
MOTOR CUR LIM:
1. With the power disconnected from the drive, connect a DC ammeter in series with the
1.
armature.
2. Set the MOTOR CUR LIM trim pot to minimum (full CCW).
3. Set the speed adjust potentiometer (full CW) or input voltage or current signal to maximum
6.
forward speed (full CW).
4. Carefully lock the motor armature. Be sure that the motor is firmly mounted.
5. Apply power source. The motor should be stopped.
6. Slowly adjust the MOTOR CUR LIM trim pot CW until the armature current is 150% of motor
6.
rated armature current.
7. Turn the speed adjust potentiometer to minimum speed (full CCW).
8. Remove power source.
9. Remove the stall from the motor.
10. Remove the ammeter in series with the motor armature if it is no longer needed.
Reverse Torque (P8 / REGEN CUR LIM): The REGEN CUR LIM setting determines the maximum torque
for decelerating the motor and resisting an overhauling load in the forward and reverse directions.
Turn the REGEN CUR LIM trim pot CW to increase the regen current limit and CCW to decrease the
regen current limit.
IR Compensation (P9 / IR COMP): The IR COMP setting determines the degree to which motor speed is
held constant as the motor load changes. It is factory set for optimum motor regulation. To calibrate
the IR COMP:
1. Set the IR COMP trim pot full CCW.
2. Increase the speed adjust potentiometer or input voltage or current signal until the motor runs
2.
at midspeed without load. A handheld tachometer may be used to measure motor speed.
3. Load the motor armature to its full load armature current rating. The motor should slow down.
4. While keeping the load on the motor, rotate the IR COMP trim pot until the motor runs at the
4.
speed measured in step 2. If the motor oscillates (overcompensation), the IR COMP trim pot
4.
may be set too high (CW). Turn the IR COMP trim pot CCW to stabilize the motor.
5. Unload the motor.
