No. Classification Name Meaning Solution
A50 Gr.1
Encoder
Disconnected The encoder may not be connected or
disconnected.
Check if the encoder
cable is connected
properly, and keep it
away from the
electromagnetic
interference.
A51 Gr.1
Overspeed
Detected
The encoder detected the Motor has
been overspeed, it may be caused by:

The battery power is too lower or
disconnected.

The value of the Motor acceleration
is too large
Reduce the Motor
speed.
A52 Gr.1
Encoder Internal
Error
There is an internal error in the
encoder. The causes nay be code wheel
contamination or damage, low encoder
supply voltage, encoder aging.
Repower up the device.
A53 Gr.1
Single-turn Data
Error
There is an internal error in the
encoder. Maybe the read and write
operations are too frequent, or internal
BUSY was set.
Repower up the device.
A54 Gr.1
Check-bit and
End-bit Error There is an error in the check-bit and
end-bit of the encoder control domain.
Repower up the device.
A58 Gr.1
Zone 1 Data
Error The data such as the phase of the
encoder zone 1 is empty or incorrect.
Replace the Motor.
A59 Gr.1
Zone 2 Data
Error

The data such as the phase of the
encoder zone 2 is empty or incorrect.

The information about the Motor
version in the encoder is incorrect.
Replace the Motor.
A65 Gr.1
Position Value
Overflow
The difference between two reference
position values is too large in IP mode
or CSP mode.
Check if the position
trajectory planning of
the master station is
correct.
A70 Gr.1 DC Sync Error
There is an error in DC
synchronization operation.
Check if the DC setting
value of the master
station is incorrect.
A71 Gr.1
SM Event Sync
Error (The event
arrived too early)
The synchronization operation of SM
Event was too early. Check the setting of the
master station.
A72 Gr.1
SM Event Sync
Error (The event
overtime)
The synchronization operation of SM
Event was overtime. Check the setting of the
master station.
A73 Gr.1
EtherCAT
Processor Error An internal error occurred in the
EtherCAT processor.
Repower up the system,
or else, contact ESTUN
or the Authorized
Distributor.
A74 Gr.1
Cycle Time Error
in Cubic
interpolation
algorithm An algorithm cycle error is detected by
the Cubic interpolation algorithm,
which is equal to the DC
synchronization period. Check if the setting of
DC synchronization
period is proper and it
shall not be 0.
