Name
During reading

0001 Inverter
response
error
There was no response from the
Inverter.
There was no response from the
Inverter.
0002 Command
bit
OFF
during transfer
The command bit turned OFF
during transfer execution, and
processing was aborted. (Note 1.)
The command bit turned OFF during
transfer execution, and processing
was aborted. (Note 1.)
0003 Transfer
execution
while busy
The transfer was executed during
busy status.
The transfer was executed during
busy status.
0004
Multiple start error
Writing and reading were both
activated at the same time
Reading and writing were both
activated at the same time
0010
CRC check error
The CRC for the read data did not
agree.
The CRC for the response from the
Inverter did not agree.
0200
Address error
An unused address was set.
An unused address was set.
0300
Data number error
An attempt was made to read
more than 8 registers at the same
time.
An attempt was made to write more
than 8 registers at the same time
2100
Data setting error
-
The write data is not within the
permissible range.
2200
Write error
-
An attempt was made during
operation to write a constant that
cannot be changed during operation.
An attempt was made to overwrite
read-only data.
2300 Write
error
(during UV)
-
An attempt was made to write a
constant during UV.
2400 Write
error
(during processing)
-
An attempt was made to write
constants when a write operation was
already in progress for the constants.
Note 1
The situation is the same when the PLC mode is changed during a data
transfer, except for cases where the status of output bits is retained when the
mode is changed.
Note
When an error occurs it is not possible to determine exactly up to what point
the data was properly received, so the data transfer must be restarted from
the beginning.
Note
When the address K (reserved in DM) is not valid, it is not possible to write
the error codes. Hence, only the error bit is set.
