7 Parameterisation of the Operating Modes
7.29 Operating mode 73: Speed setpoint PWM, distance
NOTE
In order for the parameter to function, KP_H must be > 0.
Function IN 1: Input for PWM signal.
Function IN 2: Travel distance; the distance increases with each high flank (x); displacement = x*distance.

1 1 PWM 0 - 0 S P Stop Stopping
1 1 PWM 0 -> 1 - PWM S P Distance Positioning
1 1 PWM 0 -> 1 - PWM S P Distance Positioning
Distance = Parameter 44 + 45; relative distance with plus/minus sign. Positive distances are travelled in a clockwise direction.
Travel distance only if KP_H > 0
For further information, see page 33.
Stop control = If KP_H > 0; brake and stop in the current position on changeover to IN A = IN B = 1 + Coasting rh, lh.
If KP_H = 0; brake and stop on changeover to IN A = IN B = 1, run speed to 0.
