6.6.3 Motor Potentiometer
With the motor potentiometer mode (MOP) the setpoint is controlled with the two triggers Increase and De-
crease (Example: 2 digital inputs).
The MOP is enabled by trigger P400:25 or can be set as default setpoint source.
Motor potentiometer up TRUE: Setpoint will increase with acceleration time 2
Motor potentiometer down TRUE: Setpoint will decrease with deceleration time 2
MOP is increasing/decreasing the setpoint according acceleration/deceleration time 2. The motor is following
the setpoint with acceleration/deceleration time 1 also in MOP-mode.
If both triggers are TRUE or FALSE at the same time the setpoint will remain constant.
The start value of the MOP is defined with P413:0
0:Not connected
(Reference see P400:1)
State TRUE will increase the speed setpoint in MOP-Mode.
0:Not connected
(Reference see P400:1)
State TRUE will decrease the speed setpoint in MOP-Mode.
Motor potentiometer select
0:Not connected
(Reference see P400:1)
Trigger to enable the MOP-Mode. After enabling the speed is controlled
by digital inputs MOP up / MOP down.
0: Last value
1: Init Value
2: Minimum Value
Defines the start setpoint value when MOP is enabled.
0: Last value
MOP starts with the last MOP set value.
1: Init Value
MOP starts with the value in P414:1 or P414:2
2: Minimum Value
MOP starts with minimum frequency (P210:0) or minimum PID value
