Zero Adjust (P1):
The ZERO ADJ se�ng adjusts out any non-lineari�es in the logic circuit that might arise
from component tolerances. This factory calibrated and should not need any adjustment.
Minimum Speed (P2):
The MIN SPEED se�ng determines the minimum motor speed when the speed
adjust poten�ometer or analog signal is set for minimum speed (full CCW). 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 poten�ometer or analog signal for minimum speed.
3. Adjust the MIN SPEED trim pot un�l the desired minimum speed is reached or is just at
3.
the threshold of rota�on.
Maximum Speed (P3):
The MAX SPEED se�ng determines the maximum motor speed when the speed
adjust poten�ometer or analog signal is set for maximum speed. It is factory set for maximum motor
rated speed. To calibrate the MAX SPEED:
1. Set the MAX SPEED trim pot full CCW.
2. Set the speed adjust poten�ometer or analog signal for maximum speed.
3. Adjust the MAX SPEED trim pot un�l the desired maximum speed is reached.
Check the MIN SPEED and MAX SPEED adjustments a�er recalibra�ng to verify that the motor runs at
the desired minimum and maximum speeds.
Accelera�on (P4):
The ACCEL TIME se�ng determines the �me the motor takes to ramp to a higher
speed regardless of direc�on. To calibrate the ACCEL TIME, turn the ACCEL TIME trim pot CW to
increase the forward accelera�on �me and CCW to decrease the forward accelera�on �me.
Decelera�on (P5):
The DECEL TIME se�ng determines the �me the motor takes to ramp to a lower
speed when commanded by the poten�ometer or analog signal, regardless of direc�on. To calibrate
the DECEL TIME, turn the DECEL TIME trim pot CW to increase the decelera�on �me.
Accelera�on / Motoring Torque (P6):
The MOTOR CUR LIM se�ng determines the maximum
torque (current) for accelera�ng and driving the motor in the forward or reverse direc�ons. 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 poten�ometer (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 un�l the armature current is 150% of motor
6.
rated armature current.
7. Turn the speed adjust poten�ometer 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.
Decelera�on / Regen Torque (P7):
The REGEN CUR LIM se�ng determines the maximum torque
(current) for decelera�ng the motor and resis�ng an overhauling load in the forward and reverse
direc�ons. Turn the REGEN CUR LIM trim pot CW to increase the regen current limit and CCW to
decrease the regen current limit.
PID P Gain - Kp (P8):
The constant used to scale the error feedback. It’s used to determine the
amount of error in the set speed vs. commanded speed. The lower the Kp, the more the motor speed
will drop under a load increase. However, if Kp is too high, it will cause the motor rota�on to be rough.
To calibrate the Kp:
1. Turn Kp and Ki to minimum (full CCW).
2. With the motor running, turn the Kp trim pot up (CW) un�l the motor rota�on starts to
2.
become rough. Slightly turn the Kp trim pot down (CCW) un�l motor rota�on is smooth again.
PID I Gain - Ki (P9):
The constant used to scale the sum of errors over �me. The lower the Ki, the
longer it will take motor to return to commanded speed a�er a load change. If the Ki is too high, it will
cause oscilla�on. Calibrate the Ki a�er calibra�ng Kp.

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 poten�ometer decelerates the motor from set speed to a minimum speed
determined by the MIN SPEED trim pot se�ng. 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 se�ng determines the
rate at which the drive decelerates. By closing the switch, the motor accelerates to set speed at a rate
determined by the ACCEL TIME trim pot.

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 cri�cal temperature.
6 Flashes: Overtemperature Warning - Drive’s temperature is approaching cri�cal temperature.
Maximum motor current is being reduced gradually as the drive’s temperature rises.

- Ensure that all switches and jumpers are properly set.
1. Turn the speed adjust poten�ometer full counterclockwise (CCW) or set the analog input voltage

2. Apply AC line voltage.
3. Close the enable switch and verify that the green Power LED (IL1) if flashing.
4. Slowly advance the speed adjust poten�ometer clockwise (CW) or increase the analog input voltage

input voltage or current signal is increased. Con�nue un�l the desired speed is reached.
5. Remove AC line voltage from the drive to coast the motor to a stop.

Dip Switch 1: ON - Inverted Sensors - The motor’s hall effect sensors have inverted signals.
Dip Switch 1:
OFF - Noninverted Sensors - The motor’s hall effect sensors do not have inverted signals.
If at any�me during the wiring setup and trying different hall effect combina�ons the motor runs away
in the reverse direc�on, disable the drive and toggle DIP Switch 1.
Dip Switch 2: ON - High MAX SPEED - Sets a higher maximum speed on the MAX SPEED trim pot.
Dip Switch 2:
OFF - Low MAX SPEED - Sets a lower maximum speed on the MAX SPEED trim pot.
If during calibra�on, turning the MAX SPEED trim pot fully down (fully CCW) is s�ll too high of a max
speed, then set dip switch 2 to OFF.
Dip Switch 3: ON - WigWag Mode - The poten�ometer or analog signal determines both motor speed
