• Error detection of message data
The following errors are detected in message data from the master. The inverter output is not shut off even if an error is
detected.
Error check items
NOTE
• The LF signal can be assigned to an output terminal by setting Pr.190 to Pr.195 (Output terminal function selection) .
Changing the terminal assignment may affect other functions. Set parameters after confirming the function of each terminal.
 MODBUS register
• The following shows the MODBUS registers for system environment variables (read/write), real time monitor items (read),
parameters (read/write), fault history data (read/write), and model information monitor items (read).
• System environment variables
*1 Settings in the communication parameters are not cleared.
• Converter unit status
*2 The signal within parentheses ( ) is the initial status. The description changes depending on the setting of Pr.190 to Pr.195 (Output terminal
function selection) ( page 90 ).
Error item Error description Converter unit operation
Parity error
The data received by the converter unit has different
parity from the specified one (
Pr.334 setting).
When this error occurs, Pr.343 is
incremented by one.
When this error occurs, the LF signal is
output.
Framing error
The data received by the converter unit has a different
stop bit length from the specified one (
Pr.334 setting).
Overrun error
The next data has been sent by the master before the
converter unit completes receiving the preceding data.
Message frame error
The data length of the message frame is checked, and an
error is generated if the received data length is less than
4 bytes.
CRC check error
An error is generated if the data in the message frame
does not match the calculation result.
