Function:
NOTICE
The maximum value depends on the rated
motor current.
Avoid 100% current for too long. It may
damage the motor due to overheating.
Set holding current as a percentage of the rated
motor current I in parameter 1-24 Motor

Current. Parameter 2-00 DC Hold/Motor Preheat
Current holds the motor function (holding torque)
or pre-heats the motor. This parameter is active if
DC hold is selected in parameter 1-72 Start
Function [0] or parameter 1-80 Function at Stop [1].
Function:
NOTICE
The maximum value depends on the rated
motor current. Avoid 100% current for too
long. It may damage the motor.
Set current as % of rated motor current,
parameter 1-24 Motor Current. DC-brake current is
applied on stop command, when speed is below
the limit set in parameter 2-04 DC Brake Cut In
Speed; when the DC-brake inverse function is
active (parameters 5-1* Digital Inputs are set to [5]
DC-brake inverse; or via the serial port). See
parameter 2-02 DC Braking Time for duration.
Function:
parameter 2-01 DC Brake Current, once
activated.
Function:
This parameter is for setting the DC-brake
cut-in speed at which parameter 2-01 DC
Brake Current is to be active with a stop
command.
Function:
Set current as percentage of rated motor
current, parameter 1-24 Motor Current. Active
with parameter 1-73 Flying Start. The parking
current is active during the time period set in
parameter 2-07 Parking Time.

NOTICE
Parameter 2-06 Parking Current is only
active when PM motor construction is
selected in parameter 1-10 Motor
Construction
Function:
Set the duration of the parking current time set
in parameter 2-06 Parking Current. Active in
connection with parameter 1-73 Flying Start.
NOTICE
Parameter 2-07 Parking Time is only active
when [1] PM, non-salient SPM is selected
in parameter 1-10 Motor Construction.
Function:
Off The brake resistor is not active.
AC brake AC brake is active.
Function:
[0 - 160 %] To avoid overheating of motor windings,
enter the maximum permissible current
when using AC brake.
Function:
Enable OVC during ramp down to reduce the
risk of frequency converter trip due to
overvoltage on the DC link caused by
generative power from load.
No OVC required.
Activates OVC when the frequency converter
is not in the stop state.
Activates OVC.
NOTICE
The ramp time is automatically
adjusted to avoid tripping of the
frequency converter.
