Calibration
The TORQUE setting determines the maximum torque for
accelerating and driving the motor. TORQUE is factory set at
120% of maximum drive current. You must recalibrate the
TORQUE setting if using a lower current rated motor.
1.
With no power applied to the drive, connect a DC
ammeter in series with the motor armature.
2.
Set the TORQUE trimpot to full CCW.
3.
Carefully lock the motor armature. Ensure that the motor
is firmly mounted.
4.
Apply line power. The motor should be stopped.
5.
Set the speed potentiometer or reference signal to
maximum speed. The motor should remain stopped.
6.
Slowly rotate the TORQUE trimpot clockwise (CW) until
the ammeter reads 120% of maximum motor armature
current.
7.
Set the speed adjust potentiometer or reference signal to
zero speed.
8.
Remove power from the drive.
9.
Remove the lock from the motor shaft.
10. Remove the ammeter in series with the motor armature.
Warning
Although TORQUE LIMIT is set to 120% of maximum
drive current rating, continuous operation beyond that
rating may damage the motor. If you intend to operate
beyond the rating, contact your Minarik representative for
assistance.
