Okuma Alarm-B 2165 MCS Encoder initialization failure
An error occurred in initialization of the motor encoder.

Object
Axis name or none (spindle)

Character-string
None

Code
XXYYZZZZ
XX= Encoder link sequence number at the time of error detection

0: Reset
1: Network address setting
2: Request of basic information on communication
3: Change of communication version
4: Acquisition of device information
5: Parameter change
6: AT (auto) mode start

YY= Error content

0: Communication error
1: Transmission start time over
2: Transmission finish time over
3: Reception finish time over
4: Abnormal response address
5: Abnormal response code
6: Parameter error

ZZZZ= Additional data

If YY=0, the encoder link error status C2ERR at the time of error detection appears.
If YY=1, 2, or 3, the transferred frame information QC2MTINF appears.
If YY=4, the network address of the responding device appears.
If YY=5, the received frame information QC2RXINF appears.
If YY=6, the number of parameter that caused the alarm appears.

1= Not all the necessary parameters are received.
2= Basic information on communication is incompatible.
3= Multi-rotation detection range does not match.

Probable Faulty Locations
– Motor encoder
– Encoder link cables or connectors
– Inverter unit control board
