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.
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,
XXXX: $FFFF (fix)
ZZZZ: voltage of encoder-fuse
ZZZZ: voltage of encoder-fuse
(12[V] = $9980) Normal: from 10.6 to 13.8 [V]
Permmssive: from $8800 to $B000
Probable Faulty Locations
– Full absolute scale
– Encoder link cables or connectors
– Inverter unit control board
