[MOP Increment] Parameter # 22 Factory Default 0.00 Hz/Sec [MOP Increment]
Parameter Type Read & Write Minimum 0.00 y
The MOP function is a digital solid-state circuit that
produces the same effect as rotating a speed reference
potentiometer with a small DC motor. This permits local
(HIM) or remote (TB2) control of the command
frequency. This parameter sets the rate of increase or
decrease to the [MOP Hertz] command frequency for
each input to the MOP Increment or MOP Decrement
terminals of TB2. (Requires the proper [Input Mode]
selection or serial communications.) Units 1 Hz/Sec Maximum 255 Hz/Sec
