Danfoss VLT CANopen MCA 105 Programming Guide

This parameter defines the maximum speed reference which the emergency mode can operate to, although the motor limits in
parameter 4-10 Motor Speed Direction have the highest priority. This maximum value is also used as reference value for the 8 preset
values calculations in %. If running in open loop when emergency mode is active, the unit is selected by setting parameter 0-02
Motor Speed Unit. For closed loop, select the unit in parameter 24-02 Emergency Mode Unit.
Parameter 24-05 Emergency Mode Preset Reference
Table 1042: Parameter 24-05 Emergency Mode Preset Reference
24-05 Emergency Mode Preset Reference
Default value: 0%
Parameter type: Range, -100 - 100%, Array [8]
Setup: All setups
Conversion index: -2
Data type: Int16
Change during operation: True
A parameter array with 8 elements (0–7). The 8 present values (zones) are for open-loop control. Index [0] is used for basic emergen-
cy mode control. Indexes 1–7 are used to enhance emergency mode control, which also overwrites the basic control. More refer-
ence value can be added via parameter group 24-** Application Functions 2.
Parameter 24-06 Emergency Mode Reference Source
Table 1043: Parameter 24-06 Emergency Mode Reference Source
24-06 Emergency Mode Reference Source
Default value: [0] No function
Parameter type: Option
Setup: All setups
Conversion index: -
Data type: Uint8
Change during operation: True
Select the external reference input to be used for emergency mode. In open-loop mode, this signal value is added to the preset
values in parameter 24-05 Emergency Mode Preset Reference. There may be a different units scaling between preset and external val-
ues.
