LEESON Chassis Mount Regenerative Control: 175721.00 - Manual (Page 37)

Forward Torque (FWD TQ)
The FWD TQ setting determines the maximum torque for
accelerating and driving the motor in the forward direction. It
also sets the maximum torque for decelerating the motor in the
reverse direction. Refer to the recommended FWD TQ settings
in Figure 19 on Page 36, or recalibrate using the following
procedure:
1. With the power disconnected from the drive, connect a DC
ammeter in series with the armature.
2. Set the FWD TQ trimpot to minimum (full CCW).
3. Set the speed adjust potentiometer for maximum forward speed.
4. Carefully lock the motor armature. Be sure that the motor is
firmly mounted.
5. Apply line power. The motor should be stopped.
6. Slowly adjust the FWD TQ trimpot CW until the armature
current is 120% of the motor nameplate current rating.
7. Turn the speed adjust potentiometer CCW until the motor stops.
8. Remove line power.
9. Remove the stall from the motor.
10. Remove the ammeter in series with the motor armature if it
is no longer needed.
Warning
FWD TQ should be set to 120% of the motor nameplate
current rating. Continuous operation beyond this rating may
damage the motor. The decision to change the forward
torque setting must be made after considering the gearbox
and drivetrain ratings, duty cycle, and motor characteristics.
