Section 12-3
12-3-4 Error Display for MECHATROLINK Communications Errors
This display occurs when MECHATROLINK communications are started (con-
nection established), or during communications when MECHATROLINK com-
munications are not connected correctly.
Check for disconnected, broken, or faulty contact in the MECHATROLINK
communications cables, and check the status (power interruption, etc.) of the
connected MECHATROLINK slave station devices.
Also check whether the actual connection status matches the connections
registered in the scan list.
Communications errors, scan list mismatches, or other error types, and the
axis in which the error has occurred can be checked using the PCU Error
Flags and error codes.
12-3-5 Error Display for PCU Settings and Operations
The indicator display shown in the above table indicates that illegal data is set
in the PCU parameters or an illegal operation has been attempted, such as
multistart.
This error will occur if a problem has occurred in the use of the PCU, which
requires the PCU settings or user program to be corrected.
The error types, and the axis in which the error has occurred can be checked
using the PCU Error Flags and error codes.
