8-1-2 RTEX continuous communication error protection 1 (Err. 83.0)
Th
is alarm will occur when reading error (CRC error) of the data delivered to the local node persists for the
predetermined period.
Cause • Reading error (CRC error) of the data delivered to the local node persists for the
predetermined period.
Detecting timing • When RTEX communication status is RUNNING.
• When received data is read at the communication cycle.
Internal process upon
detecting error
• Discard the received data.
• Use the previously received normal data for processing (servo is in alarm
status).
• Return Byte 1 of response as FFh.
• RTEX communication keeps RUNNING status.
▪ Because the communication continues, if the normal reception is possible
after occurrence of alarm, commands such as alarm clear can be received.
Action • Check the communication cable for excessive noises.
• Check the communication cable for length, layout arrangement, and
connections.
• Check that the communication cable is category 5-e or better shielded twisted
pair cable (STPC) specified by TIA/EIA-568.
• Replace the cable with a new one as necessary.
• Attach the ferrite core to the communication cable.
• Replace the servo driver as necessary.
Alarm clear attribute • Can be cleared.
