1 LED, red –
15 V electronics power supply faulted
2 LED, red – 5 V voltage level faulted
3 LED green – external enable signals not available
(terminal 63 and/or terminal 64 missing)
4 LED yellow – DC link charged
5 LED, red – line supply fault (single– or multi–phase supply failure at the
terminals U1, V1, W1)
1)
– commutating reactor either not available or incorrectly selected,
– fault level of the line supply or transformer too low
6 LED red – DC link overvoltage
possible causes: Regenerative feedback off, setting–up operation,
line supply fault, for UE pulsed–resistor not operational, line supply
voltage too high, dynamic overload condition
Effects:
1 red LED bright:Pulses for the complete drive group are canceled
2 red LED bright: Pulses for the complete drive group are canceled
4 yellow LED dark: xxxx
5 red LED bright: 1) Only the I/R module pulses are canceled (regenerative feedback
no longer possible. Axes first continue to run. Ready relay drops–out
6 red LED bright:Pulses for the complete drive group are canceled
1) Line supply fault identification time approx. 30ms
Line supply fault is identified for a three–phase voltage < 280V.
For 1–phase supply failure, the drive axes pulses are canceled after approx. 1 min.
