F2—Overvoltage
F2
Parameter

OK?
No
Y
es
Check parameters in G2.1, G2.4, and G2.6.
Notice the break chopper if used,
check parameter P6.3.3
No
Make corrections to the settings
Measure value =
Monitored value?
Y
es
Measure voltage in DC bus.
Compare measured voltage to
monitored value V1.8
Check current measuring circuit
according to instructions in service
manual. Replace defective parts as
recommended in the spare parts lists
Make corrective measures to
quality of line power, setting the
deceleration time versus system inertia
Fault was generated by external factor:
– line voltage >+10%
– voltage spikes on line
– feature of load
– deceleration time too short for system inertia
– break resistor too small
Clear fault memory
Note: Overvoltage trip limit is
911V in 380-500V units
