rent I
M,N
set in par.1-24
Motor Current. 100% DC holding current corre-
sponds to I
M,N
.
This parameter holds the motor (holding torque) or pre-heats the motor.
This parameter is active if [1] DC hold/Preheat is selected in par.
1-80
Function at Stop.
Note
The maximum value depends on the rated motor current.
Avoid 100 % current for too long. It may damage the motor.

50 %* [0 - 1000. %] Enter a value for current as a percentage of the rated motor current
I
M,N
, see par.1-24
Motor Current. 100% DC braking current corresponds
to I
M,N
.
DC brake current is applied on a stop command, when the speed is lower
than the limit set in par.2-03
DC Brake Cut In Speed [RPM]; when the DC
Brake Inverse function is active; or via the serial communication port.
The braking current is active during the time period set in par.2-02
