IL04 Alarm
Bits 0 to E Reserved
Bit F: User Constant Error Not used
Bit 10: Synchronization
Communication Error
Turns ON when a MECHATROLINK communica-
tions watchdog timer timeout error is detected.
Enabled when the WDT Abnormality Detection
Mask bit of the Function Selection Flag 2 fixed
parameter is set to Disabled.
This alarm can be cleared by executing Alarm
Clear.
Bit 11: Communication
Error
Turns ON when MECHATROLINK communica-
tions errors are detected continuously.
Communication Abnormality Detection Mask bit
of the Function Selection Flag 2 fixed parameter
is set to Disabled, and Alarm is selected for
Communication Selection Abnormal of the Func-
tion Selection Flag 3 fixed parameter.
This alarm can be cleared by executing Alarm
Clear.
Bit 12: Communication
Timeout Error
Turns ON when a response from the Inverter for a
command or subcommand is not detected within
five seconds.
This alarm can be cleared by executing Alarm
Clear.
Bits 13 to 15 Reserved
Bit 16: Scan Setting Error
Turns ON while the high-speed scan cycle setting
and the MECHATROLINK communications cycle
setting are asynchronous.
Bits 17 to 1B Reserved
Bit 1C: Cyclic Communi-
cation Initialize incomplete
With MECHATROLINK-III, a node can join the
network while communications are in progress.
However, conditions such as the transmission
cycle and the number of slave stations may pre-
vent a node from joining the network. If that
occurs, this bit turns ON. If this alarm occurs,
turn the power supply to the MP3000 OFF and
ON again or reset the network (OW00 bit
C).
Bit 1D: Drive Type Error
Turns ON when the Inverter model assigned in
the SVC definitions does not match the actual
Inverter model that is connected.
Bits 1E to 1F Reserved
