Calibration
Minimum Speed (MIN SPD):
The MIN SPD se�ng determines the minimum motor speed when the
speed adjust poten�ometer is set for minimum speed. It is factory set for zero speed. To calibrate the
MIN SPD:
1. Set the MIN SPD trim pot full CCW.
2. Set the speed adjust poten�ometer for minimum speed.
3. Adjust MIN SPD un�l the desired minimum speed is reached or is just at the threshold of
3.
rota�on.
If in a bidirec�onal mode (see Modes sec�on), then the MIN SPD se�ng determines the posi�on on
the external poten�ometer that will command zero speed or torque. To calibrate the MIN SPD:
1. Set the MIN SPD trim pot at 12 o’clock.
2. Set the external adjust poten�ometer at the desired zero speed/torque posi�on.
3. Adjust MIN SPD un�l the motor speed / torque is at zero.
Forward Maximum Speed (MAX SPD):
The MAX SPD se�ng determines the maximum motor speed
in the forward direc�on (when A1 is posi�ve with respect to A2). To calibrate the MAX SPD:
1. Set the MAX SPD trim pot full CCW.
2. Set the speed adjust poten�ometer for maximum speed.
3. Adjust MAX SPD un�l the desired maximum speed is reached.
Reverse Maximum Speed (REV MAX SPD):
The REV MAX SPD se�ng determines the maximum motor
speed in the reverse direc�on (when A2 is posi�ve with respect to A1). To calibrate the REV MAX SPD:
1. Set the REV MAX SPD trim pot full CCW.
2. Set the speed adjust poten�ometer for maximum speed.
3. Adjust REV MAX SPD un�l the desired maximum speed is reached.
Motoring Torque (TQ LIM):
The TQ LIM se�ng determines the maximum torque for accelera�ng and
driving the motor in the forward or reverse direc�ons. To calibrate the TQ LIM:
1. With the power disconnected from the drive, connect a DC ammeter in series with the
1.
armature.
2. Set the TQ LIM trim pot to minimum (full CCW).
3. Set the speed adjust poten�ometer to maximum 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 TQ LIM trim pot CW un�l the armature current is 150% of motor rated
6.
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.

Regening Torque (REGEN TQ LIM):
The REGEN TQ LIM se�ng determines the maximum torque for
decelera�ng the motor and resis�ng an overhauling load in the forward or reverse direc�ons. Turn
the REGEN TQ LIM trim pot CW to increase the regen current limit and CCW to decrease the regen
current limit. See the approximate se�ngs below.

Power (PWR):

Off: The drive does not have power.
Blinking (DC60-12/24-4Q): The source voltage is either below 9 VDC or above 32 VDC.
Blinking (DC60-36/48-4Q): The source voltage is either below 24 VDC or above 63 VDC.
Solid: The source voltage is within range and the drive is opera�ng correctly.
Status (CUR LIM/FAULT):
Red LED. Under some fault condi�ons, the drive may trip / disable. To reset
the drive, open and re-close the Enable connec�on or remove and re-apply the DC power source.
Solid: The drive is either in Torque Limit or Regenera�ve Torque Limit.
Con�nuous Blinking: The drive is overhea�ng. Provide more ven�la�on to the drive
or decrease the load.
2 Blinks: The drive is approaching an under-voltage trip or has entered an

1. Turn the speed adjust poten�ometer full counterclockwise (CCW).
2. Apply the source voltage.
3. Close the enable.
4. Slowly advance the speed adjust poten�ometer clockwise (CW). The motor slowly accelerates as

5. Remove the source voltage from the drive to coast the motor to a stop.
STARTUP
Startup
Speed Mode:
In Speed Mode, the drive will output whatever current (torque) is necessary to achieve
the commanded voltage (speed). The external poten�ometer on S1, S2, and S3 will vary the motor
speed as it is turned up and down. Full counterclockwise is minimum speed and full clockwise is
maximum speed. To change the motor’s direc�on, use the Direc�on Switch. To run in Speed Mode, do
not place any jumpers on the Torque Mode or Bidirec�onal Mode pins.
Speed Mode w/ Bidirec�onal Control:
Just like Speed Mode above, except now the external
poten�ometer on S1, S2, and S3 will vary the motor speed and direc�on as it is turned up and down.
Full counterclockwise is reverse maximum speed and full clockwise is forward maximum speed. The
MIN SPD trim pot is used to determine the point on the external poten�ometer that commands zero
speed. The Direc�on Switch will s�ll come into effect (ie inverts the poten�ometer). To run in Speed
Mode with bidirec�onal control, only place a jumper on the Bidirec�onal Mode pins.
Torque Mode:
In Torque Mode, the drive will output whatever voltage (speed) is necessary to achieve
the commanded current (torque). The external poten�ometer on S1, S2, and S3 will vary the motor
torque as it is turned up and down. Full counterclockwise is minimum torque and full clockwise is
maximum torque. To change the motor’s torque direc�on, use the Direc�on Switch. To run in Torque
Mode, only place a jumper on the Torque Mode pins.
Torque Mode w/ Bidirec�onal Control:
Just like Torque Mode above, except now the external
poten�ometer on S1, S2, and S3 will vary the motor torque and direc�on as it is turned up and down.
Full counterclockwise is reverse maximum torque and full clockwise is forward maximum torque. The
MIN SPD trim pot is used to determine the point on the external poten�ometer that commands zero
speed. The Direc�on Switch will s�ll come into effect (ie inverts the poten�ometer). To run in Torque
Mode with bidirec�onal control, place jumpers on both the Torque Mode and Bidirec�onal Mode pins.

IR Compensa�on (IR COMP):
The IR COMP se�ng determines the degree to which motor speed is
held constant as the motor load changes. To calibrate the IR COMP:
1. Set the IR COMP trim pot full CCW.
2. Increase the speed adjust poten�ometer un�l the motor runs at midspeed without load. A
2.
handheld tachometer may be used to measure motor speed.
3. Load the motor armature to its full load armature current ra�ng. The motor should slow down.
4. While keeping the load on the motor, rotate the IR COMP trim pot un�l the motor runs at the
4.
speed measured in step 2. If the motor oscillates (overcompensa�on), 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.
Accelera�on (ACC):
The ACC se�ng determines the �me the motor takes to ramp to a higher speed.
To calibrate the ACC, turn the ACC trim pot CW for a longer accelera�on �me and CCW for a shorter
accelera�on �me.
Decelera�on (DEC):
The DEC se�ng determines the �me the motor takes to ramp to a lower speed.
To calibrate the DEC, turn the DEC trim pot CW for a longer decelera�on �me and CCW for a shorter
decelera�on �me.
