POINT
• The axis error code among the error codes stored in the SD504 to SD506 is shown below.

(c) 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.
(d) Error detection signals and error codes are held until the error reset
command (M3207+20n) or servo error reset command (M3208+20n)
turns on.
POINT
(1) Even if the servo error reset (M3208+20n) turns on at the servo error
occurrence, the same error code might be stored again.
(2) Reset the servo error after removing the error cause of the servo amplifier side
at the servo error occurrence.
(3) Error at the real mode/virtual mode switching
These errors are checked when the real mode/virtual mode switching request
flag (M2043) turns off to on/on to off.
When the check shown in Section 9.1 and 9.2 is executed, and if error is
detected, it is as follows.
• It remains the current mode without the real mode/virtual mode switching.
• The real mode/virtual mode switching error detection flag (M2045) turns on.
• The error codes are stored in the real mode/virtual mode switching error
information (SD504 to SD506).

Erroneous axis bit "1"
<Example> For 8 axes error
(Decimal) "128" and (Hexadecimal) "0080H" is stored in the SD505,
(Decimal) "0" and (Hexadecimal) "0000H" is stored in the SD506,
and the error code is stored in the SD504.
