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.

Function:
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/Motor
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:
in 2-01 DC Brake Current, once activated.
Function:
[ 0 - 0 Set the DC brake cut-in speed for
activation of the DC braking current
