Fault Name
When (one of) the output terminal(s) is grounded, short
circuit current is larger than Pr.06-60 setting value, and
the detection time is longer than Pr.06-61 time setting,
Ground fault (GFF)
GFF occurs.
NOTE: the short circuit protection is provided for AC
motor drive protection, not to protect the user.
Action and Reset
Pr.06-60 (Default = 60%)
Pr.06-61 (Default = 0.10 sec.)
N/A
Manual reset
Reset in 5 sec. after the fault is cleared
Yes
Check the motor insulation value with megger. Replace the motor if the
insulation is poor.
Troubleshoot the short circuit.
Replace the cable.
If the motor cable length exceeds 100 m, decrease the setting value for carrier
frequency.
Take remedies to reduce stray capacitance.
Verify the grounding and wiring of the communication circuit. It is recommended
to separate the communication circuit from the main circuit, or wire in 90 degree
for effective sufficient anti-interference performance.
Cycle the power after checking the status of motor, cable and cable length. If
GFF still exists, return to the factory for repair.
Fault Name
IGBT short circuit
Short-circuit is detected between upper bridge and
between upper bridge
lower bridge of the IGBT module
and lower bridge (occ)
Action and Reset
Hardware protection
Immediately act
N/A
Manual reset
Reset in 5 sec. after the fault is cleared
Yes
Check the motor wiring.
Cycle the power, if occ still exists, return to the factory for repair.
