Number ContentsMessage
239 BP/S ALARM While punching was being performed with the function for controlling
external I/O units ,background editing was performed.
240 BP/S ALARM Background editing was performed during MDI operation.
5010 END OF RECORD The end of record (%) was specified.
2) Background edit alarm
Number Message Contents
??? BP/S alarm BP/S alarm occurs in the same number as the P/S alarm that occurs
in ordinary program edit. (070, 071, 072, 073, 074 085,086,087 etc.)
140 BP/S alarm It was attempted to select or delete in the background a program be-
ing selected in the foreground. (Note)
Use background editing correctly.
NOTE
Alarm in background edit is displayed in the key input line of the background edit screen instead
of the ordinary alarm screen and is resettable by any of the MDI key operation.
3) Absolute pulse coder (APC) alarm
Number Message Contents
300 nth–axis origin return Manual reference position return is required for the nth–axis (n=1 – 2).
301 APC alarm: nth–axis communication nth–axis (n=1 – 2) APC communication error. Failure in data trans-
mission
Possible causes include a faulty APC, cable, or servo interface mod-
ule.
302 APC alarm: nth–axis over time nth–axis (n=1 – 2) APC overtime error.
Failure in data transmission.
Possible causes include a faulty APC, cable, or servo interface mod-
ule.
303 APC alarm: nth–axis framing nth–axis (n=1 – 2) APC framing error. Failure in data transmission.
Possible causes include a faulty APC, cable, or servo interface mod-
ule.
304 APC alarm: nth–axis parity nth–axis (n=1 – 2) APC parity error.
Failure in data transmission.
Possible causes include a faulty APC, cable, or servo interface mod-
ule.
305 APC alarm: nth–axis pulse error nth–axis (n=1 – 2) APC pulse error alarm.
APC alarm.APC or cable may be faulty.
306 APC alarm: nth–axis battery voltage
0
nth–axis (n=1 – 2) APC battery voltage has decreased to a low level
so that the data cannot be held.
APC alarm. Battery or cable may be faulty.
307 APC alarm: nth–axis battery low 1 nth–axis (n=1 – 2) axis APC battery voltage reaches a level where
the battery must be renewed.
APC alarm. Replace the battery.
308 APC alarm: nth–axis battery low 2 nth–axis (n=1 – 2) APC battery voltage has reached a level where
the battery must be renewed (including when power is OFF).
APC alarm .Replace battery.
309 APC alarm: nth–axis Ern impossible For a serial a pulse coder, return to the origin is impossible because
pulse coder rotation fails to reach a single turn.
