2-00 DC Hold/Motor Preheat Current
Range:
Function:
50 %
*
[0 - 160 %]
NOTE!
The maximum value depends on the rated motor current.
Avoid 100% current for too long. It may damage the
motor.
2-01 DC Brake Current
Range:
Function:
50 %
*
[0 - 150 %]
NOTE!
The maximum value depends on the rated motor current.
Avoid 100% current for too long. It may damage the
motor.
2-02 DC Braking Time
Range:
Function:
10 s
*
[0 - 60 s] Set the duration of the DC braking current set
in
, 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 the DC braking
current
is to be
active, in connection with a stop command.
NOTE!
2-01, 2-02 and 2-04 will not have effect when
1-10 Motor
Construction
=
[1] PM, non-salient SPM
.
2-06 Parking Current
Range:
Function:
100 %
*
[0 - 150 %]
NOTE!
2-06 DC Brake Current
and
: Only
active if PM motor construction is selected in
2-07 DC Braking Time
Range:
Function:
3.0 s
*
[0.1 - 60.0 s] Set the duration of the parking current
time set in
2-06 DC Brake Current
. Active in
connection with
3.3.1 2-1* Overvoltage Control
Parameter group for selecting dynamic braking parameters.
2-10 Brake Function
Option:
Function:
[0]
Off
No brake resistor installed.
[2]
AC brake
AC brake is active.
2-17 Over-voltage Control
Option:
Function:
Select whether to enable OVC, which reduces the
risk of drive trip due to overvoltage on the DC link
caused by generative power from load.
[0] Disabled No OVC required.
[2] Enabled Activates OVC.
NOTE!
The ramp time is automatically adjusted to avoid tripping
of the Adjustable frequency drive.
NOTE!
2-17 Over-voltage Control
cannot be enabled when
1-10 Motor Construction
=
[1] PM, non-salient SPM
.
