3. POSITIONING SIGNAL
(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
stored in the minor error code storage area.(see section 3.2.1)
When a major error is detected, the corresponding error code
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
(Note-1)
stops) , and is used to determine whether or not servo errors have
occurred.
When an error is detected at the servo amplifier side, the corresponding

(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.
