Danfoss VLT AutomationDrive FC 302 Programming Guide

Enter a value for current as a percentage of the rated motor current I
M,N
, see parameter 1-24 Motor Current. 100% DC brake current
corresponds to I
M,N
. DC brake current is applied on a stop command, when the speed is lower than the limit set in parameter 2-03 DC
Brake Cut In Speed [RPM]; when the DC brake inverse function is active, or via the serial communication port. The braking current is
active during the time period set in parameter 2-02 DC Braking Time.
Parameter 2-02 DC Braking Time
Table 152: Parameter 2-02 DC Braking Time
2-02 DC Braking Time
Default value: 10 s
Parameter type: Range, 0 - 60 s
Setup: All setups
Conversion index: -1
Data type: Uint16
Change during operation: True
Set the duration of the DC brake current set in parameter 2-01 DC Brake Current, once activated.
Parameter 2-03 DC Brake Cut In Speed [RPM]
Table 153: Parameter 2-03 DC Brake Cut In Speed [RPM]
2-03 DC Brake Cut In Speed [RPM]
Default value: Size related
Parameter type: Range, 0 - par. 4-13 RPM
Setup: All setups
Conversion index: 67
Data type: Uint16
Change during operation: True
Set the DC brake cut-in speed for activation of the DC brake current set in parameter 2-01 DC Brake Current, upon a stop command.
Parameter 2-04 DC Brake Cut In Speed [Hz]
Table 154: Parameter 2-04 DC Brake Cut In Speed [Hz]
2-04 DC Brake Cut In Speed [Hz]
Default value: Size related
Parameter type: Range, 0 - par. 4-14 RPM
Setup: All setups
Conversion index: -1
Data type: Uint16
Change during operation: True
N O T I C E
Parameter 2-04 DC Brake Cut In Speed [Hz] is not effective when parameter 1-10 Motor Construction = [1] PM, nonsalient SPM.
Set the DC brake cut-in speed for activation of the DC brake current set in parameter 2-01 DC Brake Current, upon a stop command.
Parameter 2-05 Maximum Reference
Table 155: Parameter 2-05 Maximum Reference
2-05 Maximum Reference
Default value: Size related
Parameter type: Range, par. 3-02 - 999999.999 Reference- Feed-
backUnit
Setup: All setups
Conversion index: -3
Data type: Int32
Change during operation: True
This is an access parameter to parameter 3-03 Maximum Reference for legacy products. The maximum reference is the highest value
obtainable by summing all references. The maximum reference unit matches the option selected in parameter 1-00 Configuration
Mode and the unit in parameter 3-01 Reference/Feedback Unit.
Parameter 2-06 Parking Current
Table 156: Parameter 2-06 Parking Current
2-06 Parking Current
Default value: 50%
Parameter type: Range, 0 - 1000%
Setup: All setups
Conversion index: 0
Data type: Uint32
Change during operation: True
