7 Parameterisation of the Operating Modes

7.32 Operating mode 78: Speed setpoint PWM; brake

NOTE

In order for the parameter to function, KP_H must be > 0.

Function IN 1: Input for PWM signal.

Function IN 2: Input for braking voltage; motor only runs if brake released.

Speed Current limit

IN A IN B IN 1 IN 2 Direction Value Type Value Function Comment

0 0 x x - 0 - - Free-wheeling No current feed

1 0 PWM 0 - 0 S P Free-wheeling

1 0 PWM 1 pos PWM S P N control

0 1 PWM 0 - 0 S P Free-wheeling

0 1 PWM 1 neg PWM S P N control

1 1 PWM 0 - 0 S P Free-wheeling

1 1 PWM 1 - 0 S P Stop Stopping

NOTE

IN 2 = 0; brake closed

IN 2 = 1; brake open

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.

S = Static

P = Parameter

F = Freeze

D = Dynamic

x = Arbitrary value
