4.4.5 Communication error
The errors detected by inverter as relating to communication
are roughly categorized into transmission error, logic error and
communication interrupt error, and the treatment at detecting
error differs respectively.
At detecting the transmission error (error codes 71 - 73), the
information using with a negative response frame is not
performed. This is to avoid to be respond by plural inverters.
At detecting the logic error (error codes 74 - 81), the informa-
tion using with a negative response frame is performed.
Because the negative response informs the cause (content of
the error), perform the treatment (see "4.4.3 Procedure on the
host side") according to the content. However, in a case of the
option frame, the cause is not informed because of a frame
configuration of prior processing speed and having no frame
to send the cause. If necessary to treat the error every cause,
the cause can be confirmed by reading in M26 in the standard
frame. (In M26, the newest communication error code is
stored.)
(1) Communication error code
(2) Action at communication error
In case of occurring transmission errors (8 times continual) or
transmission interruption error, the following actions can be
selected. However, if not receiving the first SOH ((normal
data) after switching on of inverter power supply or not
operating by the communication (frequency command/
operation command), the error action is not performed.

Received error other than the
above errors
Incorrect transmission request

not in the specified position.
Not existing command is sent.
Intending to write operation
command in the state mounted a
link option(If a link option has
been mounted, the command data
and operation command cannot
be written through RS-485.)
Intending to write new function
data during writing from a link

Requesting not existing function
code
Intending to write the function of
forbidden writing or function of
forbidden writing in operation
during operation.
Writing data exceeded an
available range of writing.
Intending to write new function
data during writing a function.
H32 Action at occurring error Remarks
0 Immediate forced stop
1 Continue operation within
H33 time and stop
2 Continue operation till
restoration of the
communication, and
follow to designation of
communication. However,
when not restoring after
H33 time, immediate
forced stop
3 Continue operation till
restoration of the
communication, and after
the restoration, follow to
designation of communi-
cation.
