"Motor potentiometer" function

The motor potentiometer function lets the inverter respond to signal levels.

If the digital inputs "motor potentiometer up/down" are activated, the speed changes with the profile value "max. acceleration" (index 8377.21) or "max. deceleration" (index 8377.31).

The last motor potentiometer setpoint is retained even when the supply system is switched off if the "save setpoint" function is activated via index 8369.2.

If the digital inputs "motor potentiometer up/down" are activated simultaneously, there are two options:

• Save setpoint (index 8369.2): OFF:
• The inverter stops along the "max. deceleration" (index 8377.31)
• Save setpoint (index 8369.2): ON:
• The current speed is maintained.

If none of the two inputs are activated, the current speed and direction of rotation are maintained.
