A
Operations at error occurrence
There are two types of errors, stop errors and continue errors. Refer to operations at error detection for details of stop errors
and continue errors. (Page 368 Operations at error detection)
Cancelling errors
Continue errors (minor errors, or continue mode moderate errors) and warnings can be cancelled. Refer to cancelling errors
for details of cancelling errors. (Page 369 Cancelling errors)
Error codes stored using the Motion CPU
Errors detected at the Motion CPU are divided into warnings and errors. The categories and error code range of errors
detected at the Motion CPU are shown below.
• The error detection signal of the error axis turns on at the error occurrence, and the error codes are stored in the error code
storage register shown below.
• If another error occurs after an error code has been stored, the existing error code is overwritten, deleting it. However, the
error history can be checked using MT Developer2.
• Error detection signals and error codes are held until the "[Rq.1147] Error reset command (R: M34487+32n/Q:
M3207+20n)", "[Rq.1148] Servo error reset command (R: M34488+32n/Q: M3208+20n)", "[Rq.346] Command generation
axis error reset command (R: M40167+32n/Q: M10967+20n)", "[Rq.323] Synchronous encoder axis error reset (R:
M42240+8n/Q: M11600+4n)", "[Rq.2240] Machine error reset command (M43616+32m)", or "[Rq.3380] Reset command
(D54226.4+2s)" turns ON.
• When a servo error or servo warning occurs, a minor error (error code: 1C80H) or warning (error code: 0C80H) is stored in
"[Md.1005] Servo error code (R: D32008+48n/Q: D8+20n)", and servo amplifier error codes or warning codes are not
stored. Error codes or warning codes read from the servo amplifier are stored in "[Md.1019] Servo amplifier display servo
error code (R: D32028+48n/Q: #8008+20n)".
