Servo Drive Faults And Workarounds - INVT DA180-S2R8SG0 Operation Manual

DA180 series basic AC servo drive

9.1 Servo drive faults and workarounds

Code Name
Er01-0 IGBT fault
Brake pipe fault (for
Er01-1 models of 7.5kW or
above)
Er01-5 IPM fault
Possible cause
The drive actual
current exceeds
specified value.
1. Drive fault (such as drive
circuit or IGBT fault).
2. Drive cables U, V, and W
are short connected, or drive
cables are grounded
contacted improperly.
3. The motor breaks down.
4. Drive cables U, V, and W
are connected in reverse
phases.
5. Improper parameter
settings cause
divergence.
6. The ACC/DEC time in the
start or stop process is too
short.
7. Instantaneous load is too
heavy.
