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 set in
M,N
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.
Function:
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 , see parameter P-03 Motor

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.

Function:
parameter B-01 DC Brake Current, once
activated.
Function:
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).
Function:
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.
Function:
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.
Function:
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.
