| Info: | Low voltage limit |
| Data type: | REAL |
Description:
Runtime error when controller is active.
The DC bus voltage UDC_ACT sinks below the cut-off voltage 0.65 * UDC_NOMINAL.
Reaction:
Main relay opens.
The IGBT power stage is switched off.
The chopper power stage is switched off.
The holding brake is switched on.
The 'controller ready' state is reset.
Cause/Remedy:
See Power transmission
Recovery power too low: Following a power failure, the recovery power in the DC bus network is lower than the power loss of the DC bus network. -> Check the power balance.
