XXYYZZZZ
XX = FF (fixed)
YY = 00: YY = 00: Error is detected at the motor encoder.
01: Error is detected at the position encoder with shaft.
02: Error is detected at the independent position encoder.
03: Error is detected at ABSO SCALE.
02: Error is detected at the independent position encoder.
03: Error is detected at ABSO SCALE.
ZZZZ= Encoder link error status at the time of error detection.
