The errors common to the PCU can be cleared by setting the UNIT ERROR
RESET Bit in the Common Operating Memory Area, and errors that occur in
axes are cleared by setting the ERROR RESET Bit in the Axis Operating Out-
put Memory Areas.

(1) If a warning occurs in a MECHATROLINK slave device, the Warning Flag
will turn ON and operation will continue.
(2) When a connection is released by the PCU, the Servo Drive will be put in
the Servo OFF state.
(3) The operations and status for MECHATROLINK slave device errors
above indicate the PCU operation (i.e., the command sent to the slave
device when an error occurs). The operation of the MECHATROLINK
slave device in which the error occurred depends on the device's specifi-
cations.
(4) MECHATROLINK communications errors that occur in individual axes
cannot be cleared by setting the AXIS ERROR RESET Bit in the Axis Op-
erating Output Memory Areas. (For details, refer to Errors in MECHA-
TROLINK Communications in this section.)
If two or more errors occur at the same time, the errors are processed in the
order of priority starting from the most important error, as shown in the follow-
ing table, and the error codes are refreshed.
