Parameter Description

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: Function:
50 [ 0 - Enter a value for holding current as a percentage
% 160 %] of the rated motor current I
*
parameter 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 parameter 1-80 Function at Stop.
NOTICE
Parameter 2-00 DC Hold/Preheat Current does not have
effect when parameter 1-10 Motor Construction = [1] PM,
non-salient SPM.
NOTICE
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: Function:
50 [ 0 - Enter a value for current as a percentage of the
% 1000 rated motor current I
*
%] Current. 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
parameter 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
parameter 2-02 DC Braking Time.
NOTICE
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: Function:
10 s [0 - 60 s] Set the duration of the DC braking current set
*
in parameter 2-01 DC Brake Current, once
activated.

2-03 DC Brake Cut In Speed [RPM]
Range: Function:
Size [ 0 - 0 Set the DC brake cut-in speed for
related RPM] activation of the DC braking current set
*
in parameter 2-01 DC Brake Current, upon
a stop command.
When parameter 1-10 Motor Construction
is set to [1] PM non-salient SPM this
value is limited to 0 rpm (OFF)
NOTICE
Parameter 2-03 DC Brake Cut In Speed [RPM] does not
have effect when parameter 1-10 Motor Construction = [1]
PM, non-salient SPM.
2-04 DC Brake Cut In Speed [Hz]
Range: Function:
Size related [ 0 - 0.0 Hz] Set the DC brake cut-in speed for
*
activation of the DC braking current
set in 2-01 DC Brake Current, upon a
stop command.
NOTICE
Parameter 2-04 DC Brake Cut In Speed [Hz] has no effect
when parameter 1-10 Motor Construction = [1] PM, non-
salient SPM.
2-06 Parking Current
Range: Function:
50 [ 0 - Set current as percentage of rated motor
% 1000 %] current, parameter 1-24 Motor Current. Active in
*
connection with parameter 1-73 Flying Start.
The parking current is active during the time
period set in parameter 2-07 Parking Time.
NOTICE
parameter 2-06 Parking Current and
parameter 2-07 Parking Time: Only active if PM motor
construction is selected in parameter 1-10 Motor
Construction.
2-07 Parking Time
Range: Function:
3 s [0.1 - 60 Set the duration of the parking current time set
*
in parameter 2-06 Parking Current. Active in
s]
connection with parameter 1-73 Flying Start.
NOTICE
Parameter 2-07 Parking Time is only active
when [1] PM, non salient SPM is selected
in 1-10 Motor Construction
