If the motor is used with a
communication encoder, a
communication transmission
or data check error occurs
when the drive updates data
to the encoder EEPROM.
If the motor is used with a
communication encoder, no
data is found in the encoder
EEPROM when the motor
attempts to read data from it
during power-on.
If the motor is used with a

when the motor attempts to
read data from the encoder
EEPROM during power-on.

of the 2. Use the multimeter to check
whether the
voltage is less than 3.0V. If yes,
replace the battery.
3. Replace the battery when the
drive power is on. Otherwise,
encoder data may be lost.

2. Make multiple writing tries. If
the fault is reported repeatedly,
replace the motor.
1. Select the motor model based
