Fault
code
Fault type
Possible fault cause
Solution
Low grid voltage
Check the input power supply
Encoder fault occurs when PG is
running.
Check the encoder and its wiring
The servo drive power is low.
Use a servo drive with higher power
Er.oU1
Servo drive
overvoltage
during
acceleration
Abnormal input voltage
Check the input power supply
The acceleration time is too short.
Prolong the acceleration time appropriately
When instantaneous stop happens,
the rotating motor is restarted.
Set the startup mode P08.00 to startup after
speed tracking
Er.oU2
Servo drive
overvoltage
during
deceleration
The deceleration time is too short
(compared with the regenerative
energy).
Prolong the deceleration time
There is potential energy load or the
load inertial torque is large.
Select appropriate dynamic braking
components
Er.oU3
Servo drive
overvoltage at
constant speed
In vector control, the ASR parameters
are not set properly.
Refer to the ASR parameter setting of Group
P05
The acceleration/deceleration time is
too short.
Prolong the acceleration/deceleration time
appropriately
Abnormal input voltage
Check the input power supply
Abnormal fluctuation of input voltage
Install an input reactor
Large load inertia
Adopt dynamic braking components
Er.IrF
Input phase loss
There is phase loss in input R, S, T.
Check the installation wiring
Check the input voltage
Er.odF
Output phase
loss
There is phase loss in output U, V, W.
Check the output wiring
Check the motor and the cables
Er.drv
Power module
protection
There is interphase short circuit or
grounding short circuit in three
phases output.
Rewire and check the motor insulation
