Range:
*
50 % [0 - 100%]
NB!
The maximum value depends on the rated motor current.
NB!
Avoid 100 % current for too long. It may damage the motor.

Function:
Enter a value for holding current as a percentage of the rated motor current I
100% DC holding current corresponds to I
This parameter holds the motor function (holding torque) or pre-heats the motor.
This parameter is active if DC hold is selected in par. 1-80
Function:
Enter a value for current as a percentage of the rated motor current I
braking current corresponds to I .
