44 Calibration
Warning
The LOOP trimpot is used to provide additional regulation
for certain low-horsepower, high-inductance motors. It is
unused in most applications and is factory set to zero
(full CCW). Please consult your Minarik representative for
more information before adjusting this trimpot.
LOOP GAIN (LOOP)
If calibration is necessary, perform the following procedure:
1. Apply input power and set the speed adjust pot to
approximately 50% of maximum motor speed. If an input
signal is used, set the signal to approximately 50% of
maximum.
2. Adjust the LOOP trimpot slowly CW until the motor becomes
unsteady under load. A hum from the motor may be audible
at this point.
3. Slowly adjust the LOOP trimpot CCW until the motor
stabilizes and the hum (if any) is quieted. At this point, the
LOOP GAIN trimpot is adjusted to its maximum acceptable
setting and should need no further adjustment.
Calibration sequence conclusion
1. Set the speed adjust potentiometer or analog input signal to
zero speed.
2. Remove power to the drive and motor. The drive is now
calibrated for nominal operation.
