A42
Gr.1
Power Mismatch
The selection between the Drive and
Motor was mismatched.
Re-select the Motor to
match the
corresponding Drive.
A43
Gr.1
Encoder Type
Error
The data stored in the encoder E2ROM
is different from the data read from the
internal of the encoder.
Contact ESTUN or the
Authorized Distributor.
A45
Gr.1
Multi-turn Data
Error
There is a multi-turn data error in the
encoder. The cause may be code wheel
pollution, strong electromagnetic
interference.
Check if the encoder
battery is available, and
try to reset the data by
Fn010 or Fn011, then
repower up the Drive.
A46
Gr.1
Multi-turn Data
Overflow
The multi-turn data exceeded the limit
value.
Check if the encoder
battery is available, and
try to reset the data by
Fn010 or Fn011, then
repower up the Drive.
A47
Gr.1
Battery Error
(lower than
2.45V)
The battery power of the absolute
encoder is lower than 2.45V
Replace the battery
case.
A48
Gr.1
Battery Error
(lower than 3.1V)
The battery power of the absolute
encoder is lower than 3.1V
Replace the battery
case.
A49
Gr.1
Encoder Data
Abnormal
There is an internal data error in the
encoder.
Check if the encoder
battery is available, and
try to reset the data by
Fn010 or Fn011, then
repower up the Drive.
A4A
Gr.2
Encoder
Overheated
The internal temperature of encoder is
too high.
Reduce the Motor load
and improve the
cooling environment.
