Relating communication parameters
Following parameters should be set or changed if necessary.
• Baud rate (, )... Shipment setting = : 19200bps
Baud rate of all inverters in the network (master and slave) should be same network.
Baud rate of all inverters in the network (master and slave) should be same network.
• Parity () ... Shipment setting = : Even parity
Parity of all inverters in the network (master and slave) should be same network.
Parity of all inverters in the network (master and slave) should be same network.
• Communication time-out time() ... Shipment setting =
Operation is continued by the last received command value in the case of a communication break-
down. To stop the operation of inverter, provide a communication time-out time (ex. =
Operation is continued by the last received command value in the case of a communication break-
down. To stop the operation of inverter, provide a communication time-out time (ex. =
sec-
ond
) to the slave inverters. The master inverter does not trip even though the communication break-
down happens. To trip the master inverter, provide an interlock mechanism by installing a FL fault
relay point or the like from the slave side.
relay point or the like from the slave side.
• Frequency point selection (, )
Adjusted to the system.

Setting example of parameters (2-wire RS485 communication)
Parameters relating to the master side (example)
Master (transmission of output frequency
(%) (100% at FH))
Selection of communication protocol
(Toshiba inverter protocol)
Communication baud rate
(ex. 19200bps)
Parity (even parity)
Example: Panel
Example: RR/S4 input

Master (sends a torque command)
Parameters relating to the slave side (example)
Slave (If the master inverter trips, all slave inverters stop
operating.)
Selection of communication protocol
(Toshiba inverter protocol)
Communication time-out (ex. 1 second)
Communication baud rate (same to the master side)
Parity (same to the master side)
Terminal block (ex. Driven by F, ST)
( Run and stop of operation is controlled with the frequency
reference value by setting the “run frequency”.)
