7 Parameterisation of the Operating Modes

7.28 Operating mode 72: Speed setpoint PWM; dynamic current limitation via PWM

NOTE

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

Function IN 1: Input for PWM signal.

Function IN 2: selection of static / dynamic current limitation.

Speed Current limit

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

0 0 x x - 0 - - Free-wheeling No braking, no current feed

1 0 PWM 0 pos D PWM F PWM N control

1 0 PWM 1 pos F PWM D PWM N control

0 1 PWM 0 neg D PWM F PWM N control

0 1 PWM 1 neg F PWM D PWM N control

1 1 PWM 0 - 0 F PWM Stop Braking and stopping

1 1 PWM 1 - 0 D PWM Stop Braking and stopping

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.

Initialisation static current limit = I_max parameter 0x38, 0x39, 0x3A, 0x3B

Initialisation speed setpoint = 0

S = Static

P = Parameter

F = Freeze; on level changeover to IN 2 the current setpoint is frozen (saved) at IN 1.

D = Dynamic

x = Arbitrary value
