Encoder-related errors
(1) Battery voltage drop alarm
When the backup power becomes 2.7 V or less, the state LED on the controller surface
flickers in green as an alarm. If multiple axes are used, only the LED on the controller
with the relevant axis flickers in green. Error output will not turn ON.
(2) Encoder backup error
An encoder backup error occurs in the following cases. Reset input or pressing the
[CLEAR] key on the Teach Pendant can clear this error.

If the power is turned on for the first time after the main unit of axis (motor) is connected
to the controller

If the encoder cable connector is temporarily removed during backup

If the backup power becomes 2.5 V or less and normal backup cannot be done when
the power is not supplied to the controller
(3) Encoder error
An encoder error occurs in the following cases. Turn on the power again. Reset input
and pressing the [CLEAR] key on the Teach Pendant cannot clear this error.

If normal backup cannot be done because the motor rotation speed exceeds 5000 min-I

If the motor rotation speed exceeds 200 min-I during power on

If the encoder cable connector is removed or the encoder cable is disconnected while
the controller is energized
If an encoder error and encoder backup error occur, the absolute counter value will be
unreliable. Thus, the axis movement will be inhibited unless return to origin is carried out.
When these errors occur, axis movement will be inhibited unless return to origin is carried out
for all axes besides the axis for which the error occurs.
If an encoder error or encoder backup error and other error (emergency stop, etc.)
occur concurrently, the error other than the encoder-related errors may be displayed,
depending on the order of occurrence. Thus, it may not be apparent that an
encoder-related error has occurred. If the error message "RETURN TO HOME NOT
COMPLETED!" appears during axis movement after the error is cleared, an encoder
error or encoder backup error may have occurred concurrently.
