3.4 Parameters: 2-** Main Menu - Brakes
3.4.1 2-0* DC-Brakes
Parameter group for conguring the DC brake and DC hold
functions.
2-00 DC Hold/Preheat Current
Range: Function:
50
%*
[ 0 -
160
%]
NOTICE
Parameter 2-00 DC Hold/Preheat Current has
no eect 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.
Enter a value for holding current as a percentage
of the rated motor current I
M,N
set in
parameter 1-24 Motor Current. 100% DC hold
current corresponds to I
M,N
.
This parameter holds the motor (holding torque)
or preheats the motor.
This parameter is active if [1] DC hold/Motor
Preheat is selected in parameter 1-80 Function at
Stop.
2-01 DC Brake Current
Range: Function:
50
%*
[ 0 -
1000
%]
NOTICE
The maximum value depends on the rated
motor current. Avoid 100 % current for too
long. It may damage the motor.
Enter a value for current as a percentage of the
rated motor current I
M,N
, see parameter 1-24 Motor
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].
•
Parameter 2-04 DC Brake Cut In Speed
[Hz]; 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.
2-02 DC Braking Time
Range: Function:
10 s* [0 - 60 s]
Set the duration of the DC brake current set in
parameter 2-01 DC Brake Current, once
activated.
2-03 DC Brake Cut In Speed [RPM]
Range: Function:
Size
related*
[ 0 - 0
RPM]
NOTICE
Parameter 2-03 DC Brake Cut In Speed
[RPM] has no eect when
parameter 1-10 Motor
Construction=[1] PM, non-salient
SPM.
Set the DC brake cut-in speed for
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)
2-04 DC Brake Cut In Speed [Hz]
Range: Function:
Size
related*
[ 0 -
0.0 Hz]
NOTICE
Parameter 2-04 DC Brake Cut In Speed
[Hz] has no eect when
parameter 1-10 Motor
Construction=[1] PM, non-salient
SPM.
This parameter is for setting the DC brake
cut-in speed at which the DC braking
current (parameter 2-01 DC Brake Current) is
to be active in connection with a stop
command.
2-06 Parking Current
Range: Function:
50
%*
[ 0 -
1000 %]
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.
Set current as percentage of rated motor
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.
