Manual Control Adjustment
If your drive is equipped with the manual control option, the speed of the drive is
controlled by local adjustment of an internal potentiometer. To adjust the speed set point:
1. Remove and retain the M3 cover screw (1) using a small screwdriver.
2. Remove and retain the screw seal (2).
3. Insert a small screwdriver (3) into the access hole and engage the potentiometer
adjustment screw. To increase speed, rotate the adjustment clock-wise. To decrease
speed, rotate the adjustment counter-clockwise. The potentiometer is equipped with
a slip coupling which will allow the user to continue to turn the adjustment screw after
maximum and minimum speed is reached.
4. When adjustment is complete, replace the screw seal (2) and (1) the cover screw.
Tighten the cover screw to 6 in-lb (678 mNm).
