Overview of PCU Errors Section 12-1
If two or more errors of the same priority level occur at the same time, the
error status of the error that was detected first will be maintained (the error
code for the error that was detected first will be held).
Note MECHATROLINK communications errors that occur in individual axes are
processed in order of highest priority among the errors that occur in each
axis. (For details, refer to
Errors in MECHATROLINK Communications in this
section.)
The PCU functions are limited when an error occurs, as follows:
Note For PCUs with unit version 1.2 or earlier, parameters cannot be read, written,
or saved when there is an axis error. Attempts to execute these commands
