3.4 Parameters 2-** Brakes

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:
50 % [
*
160. %]
NOTE
2-00 DC Hold/Preheat Current will not have effect when
1-10 Motor Construction = [1] PM, non salient SPM.
NOTE
The maximum value depends on the rated motor current.
Avoid 100 % current for too long. It may damage the
motor.
2-01 DC Brake Current
Range:
50 [ 0 -
% 1000. %]
*
NOTE
The maximum value depends on the rated motor current.
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] Set the duration of the DC braking
*
50
Function:
0 - Enter a value for holding current as a
percentage of the rated motor current I
in 1-24 Motor Current. 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 1-80 Function at Stop.
Function:
Enter a value for current as a percentage of the
rated motor current I , see 1-24 Motor Current.
M,N
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 2-03 DC Brake Cut In Speed [RPM];
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
2-02 DC Braking Time.
Function:
current set in 2-01 DC Brake Current, once
activated.
