3.26 B-## Braking Functions
3.26.1 B-0# DC brakes
Parameter group for configuring the DC brake and DC hold
functions.
B-00 DC Hold Current
Range: Function:
50
%
*
[0 -
160 %
]
NOTICE
Parameter B-00 DC Hold Current has no
effect when parameter P-20 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 P-03 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 H-80 Function at
Stop .
B-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 P-03 Motor
Current . 100% DC brake 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 B-03 DC Brake Cut In Speed
[RPM] .
•
Parameter B-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 B-02 DC Braking Time .
B-02 DC Braking Time
Range: Function:
10 s
*
[0 - 60 s] Set the duration of the DC brake current set in
parameter B-01 DC Brake Current , once
activated.
B-03 DC Brake Cut In Speed [RPM]
Range: Function:
0 RPM
*
[0 - 0
RPM]
Set the DC brake cut-in speed for activation
of the DC braking current set in
parameter B-01 DC Brake Current , upon a
stop command.
When parameter P-20 Motor Construction is
set to [1] PM non-salient SPM , this value is
limited to 0 RPM (OFF).
B-04 DC Brake Cut In Speed [Hz]
Range: Function:
0.0 Hz
*
[0 - 0.0
Hz]
This parameter is for setting the DC brake
cut-in speed at which the DC braking
current ( parameter B-01 DC Brake Current ) is
to be active in connection with a stop
command.
B-06 Parking Current
Range: Function:
50
%
*
[0 -
1000 %]
NOTICE
Parameter B-06 Parking Current and
parameter B-07 Parking Time : Only active
if [1] PM, non salient SPM is selected in
parameter P-20 Motor Construction .
Set current as percentage of rated motor
current, parameter P-03 Motor Current . Active in
connection with parameter H-09 Start Mode . The
parking current is active during the time period
set in parameter B-07 Parking Time .
B-07 Parking Time
Range: Function:
3 s
*
[0.1 - 60
s]
Set the duration of the parking current time set
in parameter B-06 Parking Current . Active in
connection with parameter H-09 Start Mode .
NOTICE
Parameter B-07 Parking Time is only active
when [1] PM, non-salient SPM is selected
in parameter P-20 Motor Construction .
