• Error code
If any error is found in the data received by the converter unit, its error definition is sent back to the computer together with
the NAK code.
 Response time
Error
code
Error item Fault definition Converter unit operation
H0 Computer NAK error
The transmission request data from the computer was containing
errors for the permissible number of retries or more.
Output is shut off (E.PUE/
E.SER) if error occurs
continuously more than the
permissible number of retries.
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 converter unit.
H3 Protocol error
The data received by the converter unit has a grammatical
mistake. Or, data receive is not completed within the
predetermined time. CR or LF is not as set in the parameter.
H4 Framing error The stop bit length differs from the initial value.
H5 Overrun
New data has been sent by the computer before the converter unit
completes receiving the preceding data.
H6 — — —
H7 Character error
The character received is invalid (other than 0 to 9, A to F, control
code).
Does not accept the received
data. The converter unit
output is not stopped by the
fault.
H8 — — —
H9 — — —
HA Mode error
Parameter write was attempted in other than the computer link
operation mode, when operation command source is not selected
or during converter unit operation.
Does not accept the received
data. The fault does not
occur.
HB Instruction code error The specified instruction code does not exist.
HC Data range error Invalid data has been specified for parameter writing, etc.
HD — — —
HE — — —
HF Normal (no error) — —
