3.4.1 2-0* DC Brakes
Parameter group for configuring the DC brake and DC hold functions.
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.
2-01 DC Brake Current
Range:
Function:
50 %*
[0 - 1000. %]
Enter a value for current as a percentage of the rated motor current I
M,N
, see par.1-24
. 100% DC braking current corresponds to I
M,N
.
DC brake current is applied on a stop command, when the speed is lower than the limit set in par.
2-03
; when the DC Brake Inverse function is active; or via the serial
communication port. The braking current is active during the time period set in par.2-02
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.
2-02 DC Braking Time
Range:
Function:
10.0 s*
[0.0 - 60.0 s]
Set the duration of the DC braking current set in par.2-01
, once activated.
