Remote I/O Functions
When two or more parameters are being set (written), send the ENTER command just one time after
all of the parameters have been set. All of the parameters that have been set will be enabled when
the ENTER command is sent.
Note 1. In Inverters other than the 3G3MV, the parameter data will not be enabled unless the EN-
TER command is sent. In some cases, it will not be possible to start the Inverter.
Note 2. The ENTER command is required for the parameters (register numbers 0100 and higher).
Values such as the run command and frequency reference (register numbers 0000 to 000F)
are stored in the RAM area only, so that data is enabled without an ENTER command.

Special Remote I/O Responses
When data is written and read using special remote I/O, the responses shown in the following table
are returned. Check that the input data and output data match when handling communications.
Command Send format Inverter operation Remarks
ENTER command
that writes param-
eters to EEPROM Function code: 10 hex
Register number: FFFD hex
Send data: 0000 hex When the ENTER command is
received, the last string of
parameter settings data that was
received is stored in EEPROM
and enabled as operating data.
(EEPROM can be overwritten up
to 100,000 times.)
Supported by all
Inverter software.
Use this command
when you want the
data to be retained
even after the power is
turned OFF.
ENTER command
that does not write
parameters to
EEPROM Function code: 10 hex
Register number: FFDD hex
Send data: 0000 hex When the ENTER command is
received, the last string of
parameter settings data that was
received is enabled as operating
data but it is not stored in
EEPROM.
When the power is turned OFF,
the settings data is cleared and
returned to the original values.
Supported by all
Inverter software.
With the 3G3MV, the
settings data is
enabled immediately
after it is received, so it
is not necessary to
send an ENTER com-
mand.
Fault code Name Content Countermeasure
--- Normal comple-
tion response The function code and register number at
the time of transmission are placed at the
beginning, and returned with the data
amount (when data is written) or the read
data (when data is read) attached. ---
01 hex Function code
error A code other than 03 hex/08 hex/10 hex
has been set as a function code. Check and correct the
function code.
02 hex Register number
error The specified register number has not been
registered. Check and correct the reg-
ister number.
An attempt was made to read an ENTER
command register.
21 hex Data setting error An upper or lower limit for the write data
setting range was exceeded. Check the display for the
Digital Operator and cor-
rect the invalid data.
Invalid data has been set that would cause
an operation error (OPE1 to OPE9).
