Computer control
For RS-485 series communication interface, each S1100 shall be prepared with individual
communication address in Parameter 9-00, thus inverter shall control it based on the individual
communication addresses.
S1100 AC motor drive is set to Modbus networks communication, and the following two modes are
available: ASC
Ⅱ M ode( A m erican S tandard C ode for Inform ation Interchange) or R T U M ode ( R em ote
terminal Unit). Users can set specific mode and communication agreements in Parameter 9-04.
