14. Er.208: FPGA system sampling operation timeout
Cause:
•
The current sampling chip or related parameter is abnormal.
•
The communication of the encoder times out.
Cause Conrming Method Corrective Action
1. The FPGA system
sampling operation times
out
•
If the fault remains after the drive
is powered off and powered on
again several times, the servo
drive is faulty.
Replace the servo drive.
2. The communication of
the encoder times out.

15. Er.210: Output-to-ground short-circuit
Cause:
•
The drive detects motor phase current or bus voltage abnormal during self-check at power-
on.
Cause Conrming Method Corrective Action
1. The power output
cables (UVW) of the
servo drive are short-
circuited to ground.
•
Disconnect the UVW cables from
the motor, and measure whether
the motor UVW cables are short-
circuited to ground.
Connect the cables again or
replace them.
2. The motor is short-
circuited to ground.
•
Measure the insulation resistance
between the UVW of the servo
drive and the ground cable (PE)
and check whether the insulation
resistance is MΩ-level.
Replace the motor.
3. The servo drive is
faulty.
•
Remove the power cables from
the servo drive. The fault remains
after the drive is powered off and
powered on again several times.
Replace the servo drive.
16. Er.220: Internal fault
