Danfoss vlt FC 102 Programming Guide

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.
2-03 DC Brake Cut In Speed [RPM]
Range: Function:
Size
related*
[ 0 - 0 RPM] Set the DC brake cut-in speed for
activation of the DC braking current
set in parameter 2-01 DC Brake
Current, upon a stop command.
When parameter 1-10 Motor
Construction is set to [1] PM non-
salient SPM, this value is limited to
0 RPM (OFF).
2-04 DC Brake Cut In Speed [Hz]
Range: Function:
Size
related*
[ 0 - 0.0 Hz] This parameter is for setting the DC
brake cut-in speed at which the DC
braking current (parameter 2-01 DC
Brake Current) is to be active in
connection with a stop command.
2-06 Parking Current
Range: Function:
50 %* [ 0 - 1000 %]
NOTICE
Parameter 2-06 Parking Current
and parameter 2-07 Parking
Time: Only active if [1] PM,
non-salient SPM is selected in
parameter 1-10 Motor
Construction.
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.
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 with parameter 1-73 Flying
Start.
2-07 Parking Time
Range: Function:
NOTICE
Parameter 2-07 Parking Time is
only active when [1] PM, non-
salient SPM is selected in
parameter 1-10 Motor
Construction.
3.4.2 2-1* Brake Energy Funct.
Parameter group for selecting dynamic brake parameters.
Only valid for frequency converters with brake chopper.
2-10 Brake Function
Option: Function:
Available options depend on
parameter 1-10 Motor Construction:
[0] Asynchron:
•
[0] O
•
[1] Resistor brake
•
[2] AC brake
[1] PM non-salient:
•
[0] O
•
[1] Resistor brake
[0] O No brake resistor installed.
[1] Resistor brake Brake resistor incorporated in the
system for dissipation of excess
brake energy as heat. Connecting a
brake resistor allows a higher DC-
link voltage during braking
(generating operation). The resistor
brake function is only active in
frequency converters with an
integral dynamic brake.
[2] AC brake AC brake only works in compressor
torque mode in
parameter 1-03 Torque Character-
istics.
