Trim Pot Adjustments

Before the power is applied, the speed potentiometer and trim pots should be preset as follows:

TRIM POT PRESET

1) Preset trim pots in the counter-clockwise position (CCW).

2) Apply power and set GSD3-24x-3N4 power ON/OFF switches to the ON position.

3) Turn the Speed pot fully CW.

4) Adjust the MAX trim pot in the CW direction until the maximum desired speed is obtained.

5) Turn the Speed pot fully CCW.

6) Adjust the MIN trim pot in the CW direction until deadband or the desired speed is obtained.

TRIM POT ADJUSTMENT

The IR COMP trim pot is used as a regulation adjustment. If better motor regulation is needed between

minimum and maximum loads, then adjust the IR COMP trim pot as follows:

1) Turn the Speed pot CW to the 50% position.

2) Turn the IR COMP trim pot CW as needed to increase regulation.

3) Recheck and readjust the trim pots if necessary. Trim pot interaction with each other will be minimal.
