| Info: | Voltage boost factor |
| Data type: | REAL |
Description:
Runtime error if the DC bus voltage increases by a factor greater than 1.283 (= 1/(0.9*sqrt(3)/2)) when closing the main relay (see INFO).
Reaction:
None.
Cause/Remedy:
The module is operated outside the specifications:
- The switch-on interval is too short
- The DC bus capacitance is too large
- The Ambient temperature is too high.
Short-circuit in the DC bus
External charging circuit has failed
Paralleled power supply module has failed
