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.

The number of errors consecutively detected in communication
request data from the computer is greater than allowed number
of retry times.
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 the wrong protocol, data
receive is not completed within the given time, or CR and LF are
not as set in the parameter.
The stop bit length is not as specified.
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.
