E658131536 Relating communication parametersFollowing parameters should be set or changed if necessary.• Baud rate (, )... Shipment setting = : 19200bpsBaud rate of all inverters in the network (master and slave) should be same network.• Parity () ... Shipment setting = : Even parityParity 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. = 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 faultrelay point or the like from the slave side.• Frequency point selection (, )Adjusted to the system.See chapter “6.1 Speed proportional control” for details.
