Okuma Alarm-B 2198 MCS Full abso scale initialization failure
An error occurred in initialization of the full absolute scale.
Axis name or none (spindle)
XX= Encoder link sequence number at the time of error detection
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
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=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.
But,in the case that voltage of encoder-fuse is failed,
ZZZZ: voltage of encoder-fuse
Probable Faulty Locations
– Full absolute scale
– Encoder link cables or connectors
– Inverter unit control board
