encoder reports timeout.
Er02-8
Encoder fault–Encoder
battery low-voltage alarm
When a multi-turn absolute
encoder is used, the external
battery voltage of the encoder
is between 3.0V–3.2V.
1. Ensure the encoder battery
cable is connected properly.
2. Use the multimeter to check
whether the external battery
voltage is lower than 3.2V. If yes,
replace the battery.
3. Replace the battery when the
drive power is on. Otherwise,
encoder data will be lost.
Er02-9
Encoder fault–Encoder
battery undervoltage fault
When a multi-turn absolute
encoder is used, the external
battery voltage of the encoder
is between 2.5V–3.2V.
1. Ensure the encoder battery
cable is connected properly.
2. Use the multimeter to check
whether the external battery
voltage is lower than 3.0V. If yes,
replace the battery.
3. Replace the battery when the
drive power is on. Otherwise,
encoder data will be lost.
Er02-a
Encoder fault–Encoder
overheating
The encoder feedback
temperature is higher than
the temperature threshold for
protection against
overheating.
1. Ensure the temperature
threshold for protection against
overheating is correct.
2. Stop the motor to lower the
encoder temperature.
Er02-b
Encoder fault–Encoder
EEPROM writing error
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.
1. Ensure encoder cables are
connected properly and eliminate
the conditions that disturb
encoder communication.
2. Make multiple writing
attempts. If the fault is reported
repeatedly, replace the motor.
Er02-c
Encoder fault–No data in
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.
1. Select the motor model based
on the setting of P0.00 and
execute the operation of writing
data to the encoder EEPROM
through P4.97.
2. Mask this fault by setting
P4.98. The motor parameters in
