3 POSITIONING DEDICATED SIGNALS
(8) Error detection signal (M2407+20n) ............................. Status signal
(a) This signal turns on with detection of a minor error or major error, and can
be used to judge if there is an error or not.
The applicable error code
(Note-1)
is stored in the minor error code storage
register (D6+20n) with detection of a minor error.
The applicable error code
(Note-1)
is stored in the major error code storage
register (D7+20n) with detection of a major error.
(b) This signal turns off when the error reset command (M3207+20n) turns on.

(9) Servo error detection signal (M2408+20n) ................... Status signal
(a) This signal turns on when an error occurs at the servo amplifier side (except
for errors cause of alarms and emergency stops)
(Note-1)
, and can be used to
judge is there is a servo error or not.
When an error is detected at the servo amplifier side, the applicable error
code
(Note-1)
is stored in the servo error code storage register (D8+20n).
(b) This signal turns off when the servo error reset command (M3208+20n)
turns on or the servo power supply turns on again.
