• Command Error End status
(IB††093 ON and IB††0B3 ON)
Note:
The LED Indicators will be OFF when
these conditions occur in any axis.
■ Slave Mode:
MECHATROLINK Communication
Error
The meaning of this LED status is different in Master Mode and
Slave Mode.
■ Master Mode
This LED status indicates that one of the listed errors occurred in
any Servo axis.
Check the corresponding parameters to determine which error
occurred.
• Any kind of warning may cause this condition. The bits in
IL††02 indicate the cause of the warning, so it is necessary to
identify the cause of the warning, eliminate the cause, and
perform an Alarm Reset.
• Any kind of alarm may cause this condition.The bits in IL††04
indicate the cause of the alarm, so it is necessary to identify the
cause of the alarm, eliminate the cause, and perform an Alarm
Reset.
• If the Module is in Command Error End status, an error occurred
during execution of a motion command or motion subcommand.
For example, a command will end in an error if an out-of-range
command is applied. Clear the command in OW††08 or
OW††0A.

This LED status indicates that an error occurred in
MECHATROLINK communication.
Check the MECHATROLINK cable connections.
