Initial communication with the absolute position linear scale failed.
An error was detected in the communication with the detector in
absolute position detection system.
A data error was detected in absolute position detection system.
The position data have fluctuated during the absolute position
initializing.
An excessive deviation was detected between the motor end detector
and MP scale feedback data in a MP scale absolute position detection
system.
An error was detected in the offset data received from the MP scale in
a MP scale absolute position detection system.
An error was detected in the shift distance of the magnetic pole in a
linear servo system.
A data error was detected in the magnetic pole of MDS-B-HR after
passing Z-phase in a linear servo system.
