Calibration

SPEEDMASTER™ OPERATION MANUAL

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 to

zero speed.

To calibrate, turn the speed adjust potentiometer full CCW.

Adjust the MIN SPD trimpot until the motor has stopped, or is

running at the desired minimum speed.
