Motor potentiometer function
Fre
with automatic saving With this motor pot. function a setpoint value (sum) is set via the
digital inputs, which is simultaneously stored. With control
enabling R/L this is then started up in the correspondingly
enabled direction. On change of direction the frequency is
retained.
Simultaneous activation of the +/- function causes the
frequency setpoint value to be set to zero.
The frequency setpoint value can also be displayed or set in the
operating value display (P001=30, current setpoint MP-S’) or in
P718.
Any minimum frequency set (P104) is still effective. Other
setpoint values, e.g. analog or fixed frequencies can be added
or subtracted.
The adjustment of the frequency setpoint value is performed
with the ramps from P102/103.

If neither of the digital inputs is programmed for left or right enable, then the actuation of a fixed frequency or jog frequency will
enable the frequency inverter. The rotation field direction depends on the sign of the setpoint.
