Y02 SV commu er: Commu error 0051 0005
Details
A communication error has occurred between controller and drive unit.
Non-specified communication errors occurred in four consecutive communication cycles.
Remedy
- Check for any failure of the communication cable connectors.
- Check for any failure of the communication cables.
- Take measures against noise.
(Note 1) When two or more "Y02 System alarms 0051" alarms occur at the same time, only
the alarm which occurs first is displayed. Therefore, the display precedence will be as
follows: 0006, 0x04, 0005, 0x20, then 0x03.
(Note 2) Station No. always shows "0" in the alarm details, because C70 has only one
communication channel.
(Note 3) If the error is not cleared with the measures above, the drive unit may have a fault.
Take a note of the 7-segment LED contents of each drive unit and contact service
center.
