(d) Servo error detection signal (M2408+20n)
1) This signal switches ON when an error (excluding causes of warning
errors and emergency stops) is detected at the servo amplifier, and it is
used to determine if a servo error has occurred.
When an error is detected at the servo amplifier, the corresponding error
code is be stored at the servo error code storage area.
2) The servo error detection signal switches OFF when the servo error reset
signal (M3208+20n) is switched ON, or when the servo power is switched
OFF and back ON again. (Servo error reset is only effective in the REAL
mode.)

(e) Zeroing request signal (M2409+20n)
This signal switches ON when a home position address check is required at
power ON or during positioning control.
1) Other than absolute position system
i) The zeroing request signal switches ON at the following times.
• At power ON, and on resetting the servo system CPU
• During zeroing
ii) The zeroing request signal switches OFF when the zeroing is
completed.
2) Absolute position system
i) The zeroing request signal switches ON at the following times.
• During zeroing
• When a sum check error occurs (at power ON) for the backup data
(reference values).
ii) The zeroing request signal switches OFF when the zeroing is
completed.
(f) Zeroing Completed Signal (M2410+20n)
1) This signal switches ON when a zeroing designated by the servo
program or in the TEST mode is completed.
2) This signal switches OFF when a positioning start, JOG start, or manual
pulse generator start occurs.
3) If a zeroing is attempted (by the servo program) while this zeroing
completed signal is ON, the "consecutive zeroing start" error will be
activated, and the zeroing operation will not be started. (Proximity dog
type zeroing only.)
