set DIP switches SW3 and SW4 to select the closed loop voltage control response. the DIP switches should be set for the highest gain possible that yields an acceptable control response. An acceptable response should be stable and should have a minimum overshoot.response should be stable and should have a minimum overshoot. these setting are a function of the lifter and motor combination. For faster lifters use a lower gain setting. faster settings can require the use of the "Corner Hold" signal from the CNC to prevent diving in the corners. This setting affects control.
