F30017 Power section: Hardware current limit tripped too may times
Reaction: OFF2
Cause: The hardware current limit in the various phases (see A30031, A30032, A30033) has tripped
too many times. The maximum permissible number of trips depends on the power section
type.
- Control incorrectly parameterized.
- Fault in motor or in power lines.
- Power lines exceed maximum permissible length.
- Motor load too high.
- Power section defective.
