3. POSITIONING SIGNAL
3 − 11
(8) Error detection signal (M2407+20n)
(a) The error detection signal comes ON when a minor error or major error is
detected and is used to determine whether or not errors have occurred.
When a minor error is detected, the corresponding error code
(Note-1)
is
stored in the minor error code storage area.(see section 3.2.1)
When a major error is detected, the corresponding error code
(Note-2)
is
stored in the major error code storage area. (see section 3.2.1)
(b) When the error reset signal (M3207+20n) comes ON, the error detection
signal goes OFF.

REMARKS
(Note-1):For details on the error codes when minor errors occur, see Appendix 2.2.
(Note-2):For details on the error codes when major errors occur, see Appendix 2.3.
(9) Servo error detection signal (M2408+20n)
(a) The servo error detection signal comes ON when an error occurs at the
servo amplifier side (excluding errors that cause alarms, and emergency
stops)
(Note-1)
, and is used to determine whether or not servo errors have
occurred.
When an error is detected at the servo amplifier side, the corresponding
error code
(Note-1)
is stored in the servo error code storage area.
(b) The servo error detection signal goes OFF when the servo error reset signal
(M3208+20n) comes ON, or when the servo power supply is switched back
on.
