2.4.1 2-0* DC-Brakes
Parameter group for configuring the DC brake and DC hold functions.
2-00 DC Hold/Preheat Current
Range:
50 %* [0 - 160. %]
NB!
The maximum value depends on the rated motor current.
NB!
Avoid 100 % current for too long. It may damage the motor.
2-01 DC Brake Current
Range:
50 %* [0 - 1000. %]
NB!
The maximum value depends on the rated motor current.
NB!
Avoid 100 % current for too long. It may damage the motor.
2-02 DC Braking Time
Range:
10.0 s* [0.0 - 60.0 s]
2-03 DC Brake Cut In Speed [RPM]
Range:
0 RPM* [0 - par. 4-13 RPM]
2.4.2 2-1* Brake Energy Funct.
Parameter group for selecting dynamic braking parameters.
Function:
Enter a value for holding current as a percentage of the rated motor current I
1-24 Motor Current . 100% DC holding current corresponds to I
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
Function:
Enter a value for current as a percentage of the rated motor current I
rent . 100% DC braking current corresponds to I
DC brake current is applied on a stop command, when the speed is lower than the limit set in par.
2-03 DC Brake Cut In Speed [RPM]
communication port. The braking current is active during the time period set in par.2-02
Time
.
Function:
Set the duration of the DC braking current set in par.2-01
Function:
Set the DC brake cut-in speed for activation of the DC braking current set in par.2-01
Current
