SINAMICS G150
10-38
Operating Manual
Remedy:
- Check motor data, perform commissioning if necessary.
- Check motor switching mode (star/delta)
- V/f mode: Increase ramp-up.
- V/f mode: Check assignment of rated currents for motor and motor modules.
- Check power line connections.
- Check power lines for short-circuit or ground fault.
- Check length of power lines.
- Replace power section.
Acknowl.: Immediate
F30002
Power section: DC link Overvoltage
Reaction: OFF2
Cause:
Power section has detected overvoltage in DC link.
- Motor returns too much energy.
- Line voltage too high.
Remedy:
- Increase feedback time.
- Activate DC link voltage controller.
- Use braking resistor or Active Line Module.
- Activate DC link voltage controller.
- Increase current limit for infeed or use larger module (for Active Line Module).
- Check line voltage.

F30003
Power section: DC link Undervoltage
Reaction: OFF2
Cause:
Power section has detected undervoltage in DC link.
- Line failure.
- Line voltage below permissible value.
Remedy:
Check line voltage

Acknowl.: Immediate
F30004
Power section: Overtemperature Heatsink AC converter
Reaction: OFF2
Cause:
Power section temperature at heatsink of AC converter has exceeded permissible limit.
- Insufficient ventilation, fan failure.
- Overload.
- Ambient temperature too high.
- Pulse frequency too high.
Remedy:
- Check that fan is running.
- Check fan mats.
- Check that ambient temperature lies within permissible range.
- Check motor load.
- Reduce pulse frequency if higher than rated pulse frequency.
Caution:
This fault cannot be acknowledged until the value is below the warning threshold for warning
A5000.

Acknowl.: Immediate
F30005
Power section: Overload I2T
Reaction: OFF2
Cause:
Power section overloaded.
- Permissible rated current of power section exceeded permanently.
- Permissible duty cycle not observed.
