Using a motorized potentiometer as a setpoint source

Frequency setpoint via motorized potentiometer (MOP) (when P1000 = 1 -> P1031)
The 'motorized potentiometer' function simulates an electromechanical potentiometer for
entering setpoints. The value of the motorized potentiometer (MOP) can be set by means of
the "up" and "down" control commands.

Example: Implementing the motorized potentiometer using the Operator Panel keys
Description
Select the command source
1: Operator Panel keys; ON and OFF keys as well as "up" and "down" keys
Selects the frequency setpoint source
1: MOP setpoint
Setpoint memory of the MOP
The last motorized potentiometer setpoint that was active prior to the OFF command
or shutdown can be saved.
0: MOP setpoint is not saved (factory setting)
1: MOP setpoint is saved in P1040
Disables the opposite direction of the MOP
0: Reverse direction of rotation is permitted
1: Reverse direction of rotation is disabled (factory setting)
MOP setpoint
Determines the setpoint [Hz] of the motorized potentiometer (MOP). Factory setting 5
Hz
Reference frequency (Hz);
An MOP output value of 100% corresponds to the frequency setpoint of P2000.
P2000 should be changed if a maximum frequency greater than 50 Hz is required.
