Okuma Alarm-P 0863 MCS Encoder link error

Okuma Alarm-P 0863 MCS Encoder link error
An alarm occurred in encoder link communication, making it impossible to detect position or speeds.

Object
Axis name or none (spindle)

Character-string
None

Code
XXYYZZZZ
XX=FF Fixed
YY=00: An error was detected in the motor encoder.

ZZZZ= E-link error status at the time of error detection.
Each bit shows the kind communication error.
bit15 1: Communication error generated by independent encoder
bit14 1: Communication error generated by ABSOSCALE 2
bit13 1: Communication error generated by ABSOSCALE or axis-mount encoder.
bit12 1: Communication error generated by monitor encoder
bit11 Not defined
bit10 1:AT mode transmission loop error
bit9 1:Excessive number of data counts at the receiving interface
bit8 Not defined
bit7 Not defined
bit6 1: Modulation code error
bit5 1: CRC error
bit4 1: Format error
bit3 1: Double transmission error
bit2 1: Double reception error
bit1 1: Parity error
bit0 1: Time-out error

Probable Faulty Locations
– Motor encoder, ABSOSCALE, axis-mount encoder, or independent encoder of the problem axis
– Encoder link cable or connector
– Inverter unit control board
