„ ALM_CLR: 06H (Clear Alarm and Warning)
The ALM_CLR command is used to clear the alarm and warning status.
This command changes the status of the station. It does not remove the cause of a fault. After the cause of the alarm or
warning has been removed, this command is then used to clear the status of the alarm or warning.
In the following cases, a warning is generated and the command is ignored.
• If ALM_CLR_MOD is other than a set value: Data setting warning (A.94)
• If not in phase 2 or 3: Command warning (A.95)
Table 15 ALM_CLR_MOD
Note: Drive faults and alarms cannot be reset while the Drive RUN command is ON.
„ SYNC_SET: 0DH (Start Synchronous Communications)
The SYNC_SET command is used to request the start of synchronous communications. After this command is issued,
synchronous communications are carried out. If communications become asynchronous due to any fault such as a
communications fault, this command can be used to restore synchronous communications.
In the following case, a warning is generated and the command is ignored.
• If not in phase 2 or 3: Command warning (A.95)
„ CONNECT: 0EH (Connect)
The CONNECT command is used to set the communications mode and establish a connection. After the connection is
established, the phase moves to phase 2 or 3.
If a transfer fault is detected after moving to phase 2 or phase 3, notification is given of the fault. In phase 1, no
notification is given even if a transfer fault is detected. Set VER (version) to 21H (Ver. 2.1) for MECHATROLINK-II,
and to 10H (Ver. 1.0) for MECHATROLINK-I.
The communications mode is set by the COM_MOD. For details on the settings, refer to the following description.
