Acknowled.: Immediate
F30029 Power section: Motor/line filter Temperature sensor Wire break
Reaction: NONE
Cause: Connection between power section and motor/line filter temperature sensor is interrupted.
Remedy: Check temperature sensor for correct connection.
Acknowl.: Immediate
F30030 Power section: Motor/line filter temperature sensor short-circuit
Reaction: NONE
Cause: Power section motor/line filter short- circuit in temperature sensor.
Remedy: Check temperature sensor for correct connection.
Acknowl.: Immediate
A30031 Power section: Hardware current limit tripped in phase R
Cause: Current in Phase R has reached permissible current limit of power section. Pulsing is
blocked for one pulse period.
- Control incorrectly parameterized.
- Fault in motor or in power lines.
- Power lines exceed maximum permissible length.
- Motor load too high.
- Power section defective.
Remedy: - Check motor data.
- Check motor switching mode (star/delta)
- Check motor load.
- Check power line connections.
- Check power lines for short-circuit or ground fault.
- Check the length of the power lines.
A30032 Power section: Hardware current limit tripped in phase S
Cause: Current in Phase S has reached permissible current limit of power section. Pulsing is
blocked for one pulse period.
- Control incorrectly parameterized.
- Fault in motor or in power lines.
- Power lines exceed maximum permissible length.
- Motor load too high.
- Power section defective.
Remedy: - Check motor data.
- Check motor switching mode (star/delta)
- Check motor load.
- Check power line connections.
- Check power lines for short-circuit or ground fault.
- Check length of power lines.
A30033 Power section: Hardware current limit tripped in phase T
