Note that baud rate of host computer must be the same as that of AC drive.
  • Page 165 local address is set to 0 (that is, broadcast address), AC drive can only receive and execute broadcast commands of host computer, but will not respond to host computer. Modbus Response Factory default delay Pd-03 Set range 0~20ms This parameter sets interval between AC drive completing receiving data and AC drive sending data to host computer.
