2-00 DC Hold Current
Default value: 50%
Parameter type: Range, -40 - 160%
Setup: All setups
Conversion index: 0
Data type: Uint8
Change during operation: True
N O T I C E
The maximum value depends on the rated motor current. Avoid 100% current for too long. It may damage the motor. In VVC
+
control core, low values (<20%) of DC hold may result in wrong currents with larger motor sizes (>90 kW) and should be avoided.
In cases when low DC hold currents with larger motors is required, select Flux control core to ensure the right currents.
Enter a value for holding current as a percentage of the rated motor current I

set in
parameter 1-24 Motor Current
. 100% DC hold
current corresponds to I

. This parameter holds the motor function (holding torque) or preheats the motor. This parameter is ac-
tive if DC hold is selected in
parameter 1-72 Start Function [0]
or
parameter 1-80 Function at Stop [1]
.
Parameter 2-01 DC Brake Current

parameter 1-24 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 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
.
Parameter 2-02 DC Braking Time

2-02 DC Braking Time
Default value: 10 s
Parameter type: Range, 0 - 60 s
Setup: All setups
Conversion index: -1
Data type: Uint16
Change during operation: True
Set the duration of the DC brake current set in
parameter 2-01 DC Brake Current
, once activated.
Parameter 2-03 DC Brake Cut In Speed [RPM]

2-03 DC Brake Cut In Speed [RPM]
Default value: Size related
Parameter type: Range, 0 - par. 4-13 RPM
Setup: All setups
Conversion index: 67
Data type: Uint16
Change during operation: True
Set the DC brake cut-in speed for activation of the DC brake current set in
parameter 2-01 DC Brake Current
, upon a stop command.
