2-00 DC Hold/Motor Preheat Current
Range:
Function:
50 %
*
[0 -
160 %]
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
M,N
in
parameter 1-24 Motor
Current
.
Parameter 2-00 DC Hold/Motor Preheat
holds the motor function (holding torque)
or pre-heats the motor. This parameter is active if
DC hold is selected in
[0] or
parameter 1-80 Function at Stop
[1].
2-01 DC Brake Current
Range:
Function:
50
%
*
[0 -
150 %]
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
; 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.
2-02 DC Braking Time
Range:
Function:
10 s
*
[0 - 60 s] Set the duration of the DC-brake current set in
parameter 2-01 DC Brake Current
, once
activated.
2-04 DC Brake Cut In Speed
Range:
Function:
0 Hz
*
[ 0 - 400
Hz]
This parameter is for setting the DC-brake
cut-in speed at which
is to be active with a stop
command.
2-06 Parking Current
Range:
Function:
100
%
*
[0 -
150 %]
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
.
2-06 Parking Current
Range:
Function:
NOTICE
Parameter 2-06 Parking Current
is only
active when PM motor construction is
selected in
parameter 1-10 Motor
Construction
2-07 Parking Time
Range:
Function:
3 s
*
[0.1 - 60
s]
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
is only active
when
[1] PM, non-salient SPM
is selected
in
parameter 1-10 Motor Construction
.
4.3.1 2-1* Brake Energy Function
Parameter group for selecting dynamic brake parameters.
2-10 Brake Function
Option:
Function:
[0]
*
Off
The brake resistor is not active.
[2]
AC brake
AC brake is active.
2-16 AC Brake, Max current
Range:
Function:
100 %
*
[0 - 160 %] To avoid overheating of motor windings,
enter the maximum permissible current
when using AC brake.
2-17 Over-voltage Control
Option:
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.
[0]
Disabled
No OVC required.
[1]
Enabled (not
at stop)
Activates OVC when the frequency converter
is not in the stop state.
[2]
*
Enabled
Activates OVC.
NOTICE
The ramp time is automatically
adjusted to avoid tripping of the
frequency converter.
