REMARKS
For the instruction codes HFF, HEC, their set values are held once they are 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:

H00 to H6C and H80 to HEC parameter values
are changed.
H00: Pr. 0 to Pr. 99 are accessible.
H7F
H01: Communication parameter n13 (Pr. 145) and
calibration parameters C1 to C7 (Pr. 900 to
Pr. 905) are accessible.
H03: Communication parameters n1 to n12
(Pr. 331 to Pr. 342) are accessible.
HFF
H09: Communication parameters n14 to n17
(Pr. 990 to Pr. 993) are accessible.
When setting the bias/gain (data codes H5E to
H61, HDE to HE1) parameters
H6C H00: Frequency (*1)
H01: Analog
H02: Analog value of terminal (*2)
*1. The gain frequencies may also be written using
Pr. 38 and Pr. 39 (data codes A6 and A7).
HEC *2. When a voltage is given to the external
terminal to make bias or gain calibration, the
data value written is 4 digits.
The number of errors consecutively detected in
communication request data from the computer is
greater than allowed number of retries.
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.
