12 SPEEDMASTER™ OPERATION MANUAL Calibration
Calibration procedure
Calibrate the drive using the following procedure:
1. Set the MIN SPD, IR COMP, ACCEL and DECEL trimpots
to zero (full CCW).
2. Set the TORQUE trimpot to maximum (full CW).
3. Set the MAX SPD trimpot to midrange (approximate 12
o’clock position).
4. Turn the speed adjust potentiometer on front cover to zero.
5. Apply power to the drive.
6. Calibrate the trimpots as follows:
MINIMUM SPEED (MIN SPD)
The MIN SPD setting determines the motor speed when the
speed adjust potentiometer is turned full CCW or reference
signal is as its minimum. It is factory set to zero speed.
To calibrate, turn the speed adjust potentiometer full CCW or
until reference signal is at its minimum. Adjust the MIN SPD
trimpot until the motor has stopped, or is running at the desired
minimum speed.
