the EXTR instruction.
Error
code
Contents of error Inverter operation
0 Normal end (no error)
1 Inverter did not give response.
2
Timeout error. This code interlocks with M8156. Sending from inverter was aborted
midway through.
3 An unspecified station gave response.
4 The sum of data sent back by the inverter did not match.
5
In writing or reading a parameter, an improper parameter number was specified. At
this time, the error code K6702 is set to D8067.
6
Because the port is being used for another communication, it cannot be used for
communication with the inverter. At this time, the error code K6762 is set to D8067.
256
Inverter sent the error code H0. Computer NAK error.
An error was included in the transfer request data from the computer beyond the
allowable number of retries.
When errors have
occurred
consecutively beyond
the allowable number
of retries, inverter is
brought to an alarm
stop.
257
Inverter sent the error code H1. Parity error.
The contents are different from the specified parity.
258
Inverter sent the error code H2. Sum check error.
The sum check code in the computer is different from the sum value calculated from
the data received by inverter.
259
Inverter sent the error code H3. Protocol error.
Syntax error is included in the data received by the inverter, and the receiving of
data has not been completed within the specified time, or CR/LF does not agree
with the parameters.
260
Inverter sent the error code H4. Framing error.
The stop bit length is different from the initial set value.
261
Inverter sent the error code H5. Overrun error.
Before receiving the completed data in the inverter, the computer sent the next set
of data.
262
Inverter sent the error code H6.
Not defined currently in inverter.
263
Inverter sent the error code H7. Character error.
An unused character (other than 0 to 9, A to F and control codes) was received.
Inverter does not
accept the received
data, but is not
brought to an alarm
stop.
