errors.
(4) 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 it is used as
judgement of the servo error available/not available.
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 (Refer to
Section 4.2.1).
(b) This signal turns off when the servo error reset command (M3208+20n)
turns on or the servo power supply turns on again.
(Servo error reset is valid in the real mode only.)

(5) Home position return request signal (M2409+20n)
........................ Status signal
This signal turns on when it is necessary to confirm the home position address.
(a) When not using an absolute position system
1) This signal turns on in the following cases:
• Multiple CPU system power supply on or reset
• Servo amplifier power supply on
• Home position return start in the real mode
(Unless a home position return is completed normally, the home
position return request signal does not turn off.)
2) This signal turns off by the completion of home position return.
