Parameter Description

3.4 Parameters 2-** Brakes

3.4.1 2-0* DC Brakes
Parameter group for configuring the DC brake and DC
hold functions.
2-00 DC Hold/Preheat Current
Range:
50 % [ 0 - 160 %]
*
NOTICE!
2-00 DC Hold/Preheat Current will not have effect when
1-10 Motor Construction = [1] PM, non-salient SPM.
NOTICE!
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:
50 % [ 0 - 1000 %]
*
NOTICE!
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 2-01 DC Brake Current, once activated.
2-03 DC Brake Cut-in Speed [RPM]
Range: Function:
Size related [ 0 - 0 Set the DC brake cut-in speed for
*
RPM] activation of the DC braking current
set in 2-01 DC Brake Current, upon a
stop command.
When 1-10 Motor Construction is set to
[1] PM non-salient SPM, this value is
limited to 0 rpm (OFF)
NOTICE!
2-03 DC Brake Cut-in Speed [RPM] will not have effect when
1-10 Motor Construction = [1] PM, non-salient SPM.
2-04 DC Brake Cut-in Speed [Hz]
Range:
Size related [ 0 - 0.0 Hz]
*

NOTICE!
2-04 DC Brake Cut-in Speed [Hz] will not have effect when
1-10 Motor Construction = [1] PM, non-salient SPM.
2-06 Parking Current
Range:
50 %
Function:
NOTICE!
2-06 Parking Current and 2-07 Parking Time: Only active if
PM motor construction is selected in 1-10 Motor
Construction.
2-07 Parking Time
Range:
3 s
3.4.2 2-1* Brake Energy Funct.
Function:
Parameter group for selecting dynamic braking parameters.
Only valid for adjustable frequency drives with brake
chopper.
2-10 Brake Function
Option: Function:
[0] Off No brake resistor installed.
2-11 Brake Resistor (ohm)
Range:
Size
related
Function:

MG20O622 - VLT is a registered Danfoss trademark
[ 0 - 1000 %]
*
Function:
[0.1 - 60 s] Set the duration of the ing current time set in
*
2-06 Parking Current. Active in connection with
1-73 Flying Start.
Available selections depend on 1-10 Motor Construction:
[0] Asynchron:
[0] off
[1] Resistor brake
[2] AS brake
[1] PM non-salient:
[0] off
[1] Resistor brake
Function:
[ 5.00 - Set the brake resistor value in Ohms.
65535.00 This value is used for monitoring the
*
Ohm] power to the brake resistor in
2-13 Brake Power Monitoring. This
parameter is only active in adjustable
frequency drives with an integral
dynamic brake.
Use this parameter for values without
decimals. For a selection with two
decimals, use 30-81 Brake Resistor
(ohm).
