Determines the treatment when an error is detected that the host controller does not continuously transmit data to
the AC motor drive during Modbus communication. The detection time is based on the Pr.09-03 setting.
When a transmission error occurs (for example, the error code CE10 displays), the error remains even if the
transmission status returns to normal, and is not cleared automatically. In this case, set a reset command (Reset)
to clear the error.
