Probable Cause Conrming Method Corrective Action
2. Current sampling
times out.
Internal fault code 200B-2Eh =
3208:
Check whether there is large
equipment generating interference
on-site and whether there are
interference sources such as
various variable-frequency devices
inside the cabinet.
The internal current sampling chip
is damaged.
Separate the heavy current from the
light current.
Replace the servo drive.
3. FPGA operation
times out.
Internal fault code 200B-2Eh =
0208:
Determine causes 1/2/3.
Remove the preceding causes 1/2/3.
E1.210: Output to-ground short-circuit
Cause:
The servo drive detects abnormal motor phase current or bus voltage during self-check at
power-on.
Probable Cause Conrming Method Corrective Action
1. The servo
drive power
cables (UVW)
are short-
circuited to
ground.
Disconnect the motor cables, and
measure whether the servo drive power
cables (UVW) are short-circuited to
ground (PE).
Re-connect these cables or
replace them.
2. The motor is
short-circuited to
ground.
After ensuring that the servo drive
power cables and motor cables are
connected securely, measure whether
the insulation resistance between the
servo drive UVW cables and ground
cable (PE) is at the MΩ level.
Replace the motor.
3. The servo
drive is faulty.
Remove the power cables from the
servo drive. The fault persists after the
drive is powered off and on several
times.
Replace the servo drive.
E1.220: UVW phase sequence incorrect
Cause:
Incorrect UVW phase sequence is detected during angle auto-tuning.
Probable Cause Conrming Method Corrective Action
Power cable
sequences are
incorrect.
Check whether power cable
sequence are correct.
Change any two phase sequences
for angle auto-tuning again.
E1.234: Runaway
Cause:
The torque reference direction is reversed to the speed feedback direction in the torque
control mode.
The speed feedback direction is reversed to the speed reference direction in the position or
speed control mode.
