RXnA turns ON when a warning occurs.
When no warning has occurred, RXnA turns OFF within about 1s after
power-on.
RXnB turns ON when Open battery cable warning (A92) or Battery warning
(A9F) occurs. When no battery warning has occurred, RXnB turns OFF
within about 1s after power-on.
RXnC turns ON when In position (RXn1) turns ON and the command
remaining distance is "0".
RXnC turns ON at servo-on.
RXnD turns off simultaneously when the dynamic brake is operated. When
using the external dynamic brake on the servo amplifier of 11kW or more,
this device is required. (Refer to section 14.6.) For the servo amplifier of
7kw or less, it is not necessary to use this device.
Refer to Speed instruction execution demand (RY(n 2)0).
Refer to Position instruction execution demand (RY(n 2)1).
As soon as the movement completion (RXnC) turns on, the station number
is output in 8-bit code.

2. All station outputs turn to "0" (OFF) when the current position is
out of the in-position range.
At power-on, emergency stop or alarm occurrence, if the current position is
within the in-position range of each station, corresponding station number
is output.
While operating in the automatic operation mode, if the current position is
within the in-position range of the target next station, corresponding station
number is output.
While operating in the indexer JOG operation of manual operation mode, if
the current position is within the in-position range of the station where the
servo motor stops by turning off the start (RYn1), corresponding station
number is output.
When home position return is incomplete, station number is not output.
