Function:
* [0 - 100%] Enter a value for holding current as a percentage of the rated
motor current I
holding current corresponds to I
This parameter holds the motor function (holding torque) or
pre-heats the motor.
This parameter is active if
tion at Stop
NB!
The maximum value depends on the rated motor current.
NB!
Avoid 100 % current for too long. It may damage the motor.
