REMARKS
Once the HFF, HEC or HF3 instruction code is written, the set value is held, but is reset 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 form the computer.
Error
Code
Item Definition Inverter Operation
H0 Computer NAK error
The number of errors consecutively detected in communication
request data from the computer is greater than allowed number
of retry times.
H1 Parity error The parity check result does not match the specified parity.
H2 Sum check error
The sum check code in the computer does not match that of the
data received by the inverter.
H3 Protocol error
Data received by the inverter is in the wrong protocol, data
receive is not completed within the given time, or CR and LF are
not as set in the parameter.
H4 Framing error The stop bit length is not as specified.
H5 Overrun error
New data has been sent by the computer before the inverter
completes receiving the preceding data.
Brought to an alarm stop
(E.OPT) if error occurs
continuously more than
the allowable number of
retry times.
H6
H7 Character error
The character received is invalid (other than 0 to 9, A to F,
control code).
Does not accept receive
data but is not brought to
alarm stop.
H8
H9
HA Mode error
Parameter write was attempted in other than the computer link
operation mode or during inverter operation.
HB

error
The specified command does not exist.
HC Data range error
Invalid data has been specified for parameter write, frequency
setting, etc.
Does not accept or
receive data but is not
brought to alarm stop.
