Increase Decrease Reset
Frequently used for pendant stations on cranes, MOP control generates a speed reference for the G7
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 time greater than 10 seconds.
The following programming example will demonstrate how to set up a G7 to function as a MOP
operator.
