Communication Error (Ce) - YASKAWA GPD 515/G5 Modbus RTU Technical Manual

Communication Error
Once the data, sent from the master device, is received the drive, the received data is checked for
CRC, parity, overrun, framing, and receiving buffer overflow. If all checked items pass, the data
has been received normally. A communication error is declared if any of the checked data does
not pass. A time-out detection can also cause a communication error. A time-out occurs if the
drive does not receive a valid message addressed to itself within two seconds. A time-out will
only cause a communication error if enabled by parameter H5-05 (as shown below).
