Description of Fault Codes

Cause
Confirming Method
Solution
1. FPGA internal speed
overflows.
Check whether the servo
drive power cables are
connected in the correct
sequence at both ends.
Connect the U/V/W cables in
the correct phase sequence.
2. The motor speed
overshoots.
Check in the software tool
whether the speed feedback
exceeds the overspeed
threshold.
Adjust the gains or
mechanical operating
conditions.
3. FPGA speed measurement
is abnormal.
Check whether bit9 of
H0b.30 is 1.
1. The speed feedback is
abnormal, check whether
the encoder version
(H00.04) is set properly.
2. The encoder cable is
abnormal, replace the
encoder cable.
3. The encoder cable is
being disturbed. Re‑
connect the grounding
cable and the shielded
cable or install a magnetic
ring.
● E500.2: Velocity feedback error 2
Cause
Confirming Method
Solution
Communication error
occurred between boards of
the drive.
The alarm persists in spite of
repeated power off and on.
Replace the servo drive.
● E602.0: Angle auto‑tuning error
Cause:
Unusual jitter occurs on the encoder feedback during angle auto‑tuning.
Cause
Confirming Method
Solution
The data fed back by the
encoder is abnormal.
Check if the encoder
communication is being
disturbed.
Check the wiring of the
encoder.
● E602.2: Wrong phase sequence detected during angle auto‑tuning
Cause:
A wrong U/V/W phase sequence is detected during angle auto‑tuning.
