The REJOIN command bit can be used when the Connection Status Flag is
ON (i.e., when a connection is established).
When executing processing for an axis to rejoin a connection, the Unit Busy
Flag will turn ON for a minimum of one scan time and until the Axis Communi-
cations Status Flags turn ON for the axes being processed or until a MLK ini-
tialization error (Unit error code: 0020 (hex)) occurs after the REJOIN
command bit is turned ON.
Note
When the REJOIN command is executed, processing to restart MECHA-
TROLINK communications is performed for all specified axes. If there are any
axes for which MECHATROLINK communications cannot be started, commu-
nications errors will not occur for individual axes, but rather an MLK initializa-
tion error (Unit error code: 0020 (hex)) will occur for the entire Unit. If
MECHATROLINK communications cannot be restarted when attempting to
recover from communications errors for only specific axes, the error status will
thus change from one for specific axes before rejoin processing to one for the
entire Unit after rejoin processing. Monitor the status of these error flags to
determine the result of rejoin processing.
