Error item
The number of errors consecutively detected in
communication request data from the computer is greater
than the permissible 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.
The data received by the inverter has a grammatical mistake.
Or, data receive is not completed within the predetermined
time. CR or LF is not as set in the parameter.
The stop bit length differs from the initial setting.
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, when operation command source is not
selected or during Inverter operation.
The specified instruction code does not exist.
Invalid data has been specified for parameter writing, running
frequency setting, etc.

continuously more than the
permissible number of retries.
The LF signal is output.
The inverter does not accept the
received data. However, the
inverter output is not shut off.
