REMARKS
For the instruction code HFF, its set value is held once it is written, but changed to 0 when the
inverter is reset or all clear is performed.
<Error Code List>
The corresponding error code in the following list is displayed if an error is detected in
any communication request data from the computer.

Code
H00 to H6C and H80 to HEC parameter values are
changed.
H7F
H00: Pr. 0 to Pr. 99 values are accessible.
H01: Pr. 145 value is accessible.
H03: Pr. 331 to Pr. 342 values are accessible.
HFF
H05: Pr. 503 to Pr. 533 values are accessible.
H09: Pr. 990 to Pr. 993 values are accessible.
The number of errors consecutively detected in
communication request data from the
computer is greater than allowed number of
retries.
The parity check result does not match the
specified parity.
The sum check code in the computer does not
match that of the data received by the inverter.
Data received by the inverter is in wrong
protocol, data receive is not completed within
given time, or CR and LF are not as set in the
parameter.
The stop bit length is not as specified by
initialization.
New data has been sent by the computer
before the inverter completes receiving the
preceding data.
The character received is invalid (other than 0
to 9, A to F, control code).
Parameter write was attempted in other than
the computer link operation mode or during
inverter operation.
The specified command does not exist.
Invalid data has been specified for parameter
write, frequency setting, etc.
