p0278 DC link voltage undervoltage threshold reduction / Vdc U_under red
Access level: 3
Can be changed: T
Units group: -
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
Refer to: F30003
Notice: When using a Control Supply Module (CSM) for 24 V supply from the DC link, the minimum continuous DC link volt-
age 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.
p0287[0...1] Ground fault monitoring thresholds / Gnd flt threshold
Access level: 3
Can be changed: T
Units group: -
Min
0.0 [%]
Description: Sets the shutdown thresholds for the ground fault monitoring.
The setting is made as a percentage of the maximum power unit current (r0209).
Index: [0] = Threshold at which pre-charging starts
[1] = Threshold at which pre-charging stops
Dependency: Refer to: F30021
r0289 CO: Maximum power unit output current / PU I_outp max
Access level: 3
Can be changed: -
Units group: -
Min
- [Arms]
Description: Displays the actual maximum output current of the power unit taking into account derating factors.
