2.5. Parameters: Brakes
2.5.1. 2-** Brakes
Parameter group for setting brake features in the frequency converter.
2.5.2. 2-0* DC-Brakes
Parameter group for configuring the DC brake and DC hold functions.
2-00 DC Hold 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. 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

NB!
The maximum value depends on the rated motor current.
NB!
Avoid 100 % current for too long. It may damage the motor.
