Motor Operated Pot2 (MOP)
Introduction
Frequently used for pendant stations on cranes, MOP control generates a speed reference for the G3 based on
how long a momentary contact is made. When the “increase” contact is made, the drive increases its output
frequency until the contact is released, at which point it maintains the current frequency. When the “decrease”
contact is made, the drive decreases its output frequency until the contact is released, at which point it
maintains the current frequency. A closure of the momentary “reset” contact ramps the drive down to zero
hertz. Do not use this control scenario with ACCEL and/or DECEL times greater than 10 seconds.
