7.5.11.5 Setpoint input via function ”Motor potentiometer in
combination with JOG value”
Function The setpoint input via the function ”Motor potentiometer in combination with JOG value” is only
active, if C007 is set accordingly (see chapter 7.8, ”Code table”).
The field frequency is changed:
- For acceleration over acceleration ramp C012.
- For deceleration:
- via the deceleration ramp C013 (820X controllers),
- via the quick-stop ramp C105 (821X/822X/824X controllers).
Activation C007 = -22-:

Important - In the event of maloperation, i.e. UP = E2 and DOWN = E3 both activated, the controller is set to
0 Hz.
- The field-frequency value activated via the motor-potentiometer function represents the max. limit
value for the JOG function E1, i.e. it is not possible to activate a JOG value higher than the last
motor-potentiometer value. Smaller values are however possible.
- In the event of mains disconnection (interruption > approx. 10 s) the last motor potentiometer
value will not be stored, i.e. the new start value is 0 Hz.
- With CCW rotation (E3 = 1, E4 = 1) the ”DOWN” function changes from E3 = 1 to E4 = 0.
Special features The function can be influenced through level inversion of the terminals (C114).
