Parameter group for configuring the DC brake and DC hold functions.
2-00 DC Hold Current/Preheat Current
Range:
Function:
50 %
*
[0 - 100%]
Enter a value for holding current as a percentage of the rated
motor current I
M,N
set in par. 1-24 Motor Current. 100% DC
holding current corresponds to I
M,N
.
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
Func-
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.
