7 Parameterisation of the Operating Modes
7.12 Operating mode 26: dynamic current limit via A1; rotational direction
NOTE
In order for the parameter to function, KP_H must be > 0.
Function IN 1: selection of static / dynamic current limitation.
Function IN 2: Selecting the rotational direction.

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 1 the current level is frozen (saved) at A1.
D = Dynamic
x = Arbitrary value
