Error
code
Inverter sent the error code H0. Computer NAK error.
256 An error was included in the transfer request data from the computer beyond the
allowable number of retries.
Inverter sent the error code H1. Parity error.

The contents are different from the specified parity.
Inverter sent the error code H2. Sum check error.
258 The sum check code in the computer is different from the sum value calculated
from the data received by the inverter.
Inverter sent the error code H3. Protocol error.
Syntax error is included in the data received by the inverter, and the receiving of
259
data was not completed within the specified time, or CR/LF does not agree with
the parameters.
Inverter sent the error code H4. Framing error.
260
The stop bit length is different from the initial set value.
Inverter sent the error code H5. Overrun error.
261 Before receiving the completed data in the inverter, the computer sent the next
set of data.
Inverter sent the error code H6.
262

12.4.10 Inverter communication error occurrence step [D8153 and D8158]

These devices store the step number in which an inverter communication error has occurred.
1. Detailed contents
D8153 or D8158 stores the step number of the instruction causing an inverter communication error.
D8153 stores the step number in which an error has occurred in communication using communication port
ch1.
D8158 stores the step number in which an error has occurred in communication using communication port
ch2.
When errors that occurred in two or more instructions, D8153 or D8158 holds the step number in which the
error occurred first.
When no error has occurred, D8153 or D8158 stores "-1".
2. Cautions on use
A decimal value without the sign is stored as the step number in D8153 and D8158.
