2-00 DC Hold/Preheat Current
Range:
Function:
50 %*
[0 - 160. %]
Enter a value for holding current as a percentage of the rated motor current I
M,N
set in par.
. 100% DC holding current corresponds 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
NOTE!
The maximum value depends on the rated motor current.
NOTE!
Avoid 100% current for too long, as it may damage the motor. It may damage the motor.
