RS-485 Communication Features
Set a communication configuration. Set the data length, parity check
method, and the number of stop bits.
8-bit data / no parity check / 1 stop bit
8-bit data / no parity check / 2 stop bits
8-bit data / even parity / 1 stop bit
8-bit data / odd parity / 1 stop bit
Set the response time for the slave (inverter) to react to the request from
the master. Response time is used in a system where the slave device
response is too fast for the master device to process. Set this code to an
appropriate value for smooth master-slave communication.
Setting Operation Command and Frequency
To select the built-in RS485 communication as the source of command, set the Frq code to
6 (Int485) on the keypad (basic keypad with 7-segment display). On an LCD keypad, set
the DRV code to 3 (Int485). Then, set common area parameters for the operation
command and frequency via communication.
