DC link voltage undervoltage threshold reduction / Vdc U_under red

VECTOR_G Can be changed: T
Data type: FloatingPoint32
P-Group: Converter
Not for motor type: -
Min
-80 [V]
Description: Sets the absolute value by which the threshold to initiate the undervoltage fault (F30003) is reduced.
Dependency: Refer to: p0210, r0296
Notice: When using a Control Supply Module (CSM) for 24 V supply from the DC link, the minimum continuous DC link
voltage may not lie below 430 V. DC link voltages in the range 300 ... 430 V are permissible up to a duration of 1 min.
For chassis power units, this parameter has no significance.
Note: The resulting shutdown threshold can be read in r0296 and is dependent on the selected rated voltage (p0210) and
the power unit being used.
p0279

DC link voltage offset alarm threshold / Vdc offs A thresh

B_INF Can be changed: T
Data type: FloatingPoint32
P-Group: Converter
Not for motor type: -
Min
0 [V]
Description: Sets the voltage threshold to initiate alarm A06810.
The value represents an offset so that the alarm threshold is obtained from the total of r0296 and p0279.
Dependency: Refer to: p0210, r0296
Note: The absolute value of the undervoltage threshold r0296 depends on the selected unit supply voltage (p0210).
p0287[0...1]

Ground fault monitoring thresholds / Gnd flt threshold

VECTOR_G Can be changed: T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [%]
Description: Sets the shutdown thresholds for the ground fault monitoring.
The setting is made as a percentage of the maximum current of the power unit (r0209).
Index: [0] = Threshold at which pre-charging starts
[1] = Threshold at which pre-charging stops
Note: The parameter only applies to booksize and chassis power units.
De-activating the ground fault monitoring:
- Sequence: --> p0287[1] = 0 --> p0287[0] = 0
- irrespective of the firmware version of the power unit.
Sets the thresholds:
- the prerequisite is at least firmware version 2.2 of the power unit.
