The REVERSE TORQUE setting determines the maximum current
limit for driving the motor in the reverse direction. It is factory set at
120% of maximum rated motor current. Refer to Figure 15 on
page 33 for recommended settings or use the following procedure
to recalibrate REVERSE TORQUE:
1. With the power disconnected from the drive, connect a DC
ammeter in series with the armature.
2. Set the REVERSE TORQUE trimpot to mminimum (full CCW).
3. Set the speed adjust potentiometer to maximum (full CW).
4. Carefully lock the motor armature. Be sure tha the motor is
firmly mounted.
5. Apply line power. The motor should be stopped.
6. Slowly adjust the REVERSE TORQUE trimpot CW slowly until
the armature current is 120% of motor rated armature current.
7. Set the speed adjust potentiometer to minimum.
8. Remove the power from the drive and unlock the motor shaft.
9. Remove the ammeter in series with the motor armature if it is
no longer needed and re-apply power to the drive.
REVERSE TORQUE
Warning
Although REVERSE TORQUE can be set to 120% of motor
nameplate current rating, continuous operation beyond this
rating may damage the motor. If you intend to operate beyond
this rating, contact your Minarik representative for assistance.
