An error occurred in the VDU(Vibration Detect Unit) communication link, disabling the VDU from detecting acceleration.
Object
Axis name or none (spindle)
Character-string
None
Code
XXYYZZZZ
XX = FF [HEX] (fixed)
YY = 00 [HEX] (fixed)
ZZZZ = VDU link error status at the time of error detection.
(Each bit represents the kind of communication error.)
