Calibration
Calibration procedure
Calibrate the drive using the following procedure:
1. Set the MIN SPD, MAX SPD, ACCEL and DECEL
trimpots to zero (full CCW).
2. Set the TORQUE trimpot to maximum (full CW).
3. Set the IR COMP trimpot to midrange (approximate 12
o’clock position).
4. Set the signal input (analog voltage signal or speed adjust
potentiometer) 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. It is factory set
for zero rated speed.
To calibrate, set the MIN SPD trimpot full CCW. Set the speed
adjust potentiometer or reference signal to minimum. Adjust
the MIN SPD trimpot until the desired minimum motor speed
is reached.
