Parameter Group 2-** Brakes - Danfoss VLT Flow Drive FC 111 Programming Manual

VLT® Flow Drive FC 111
Programming Guide
Select the input at which the thermistor (PTC sensor) should be connected. When using an analog input, the same analog cannot be
used as a reference in parameter 3-15 Reference Resource 1 to parameter 3-17 Reference Resource 3, parameter 20-00 Feedback 1 Source,
parameter 20-03 Feedback 2 Source, parameter 24-06 Fire Mode Reference Source, and parameter 24-07 Fire Mode Feedback Source.

4.4 Parameter Group 2-** Brakes

4.4.1 2-0* DC-Brake
Parameters for configuring the DC brake and DC hold functions.
2-00 DC Hold/Motor Preheat Current
Default value: 50%
Conversion index: -
MOTOR OVERHEATING
The maximum value depends on the rated motor current.
-
To avoid motor damage caused by overheating, do not run at 100% for too long.
Set holding current as a percentage of the rated motor current I
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] DC Hold/delay time or parameter 1-80 Function at Stop [1] DC hold/Motor Preheat.

Min: 0%
2-01 DC Brake Current
Default value: 50%
Conversion index: -
MOTOR OVERHEATING
The maximum value depends on the rated motor current.
-
To avoid motor damage caused by overheating, do not run at 100% for too long.
Set current as % of rated motor current, parameter 1-24 Motor Current. When speed is below the limit set in parameter 2-04 DC Brake
Cut In Speed, or when the DC-brake inverse function is active (in parameter group 5-1* Digital Inputs set to [5] DC-brake inverse; or via
the serial port), a DC brake current is applied on a stop command. See parameter 2-02 DC Braking Time for duration.

2-02 DC Braking Time
Default value: 10 s
Conversion index: -1
