Communication Setting Between Option Board; Communication Error Detection Between Inverter And Option Board; Selection Of The Communication Protocol (F829); Number Of Motor Poles For Communication (F856) - Toshiba TOSVERT VF-FS1 series Function Manual

3.2. Communication setting between option board

Do not change communication rate (f800), parity (f801) and communication waiting time
(f805) from shipment setting. If change the setting, the option board does not work properly.

3.3. Communication error detection between inverter and option board

Set the communication loss action time to f803 between the inverter and the option board. And the
network communication loss action time to f892. The network loss action function starts from
receiving the properly frame message. The action of the network communication loss is set by f851.
When set the communication loss action time f803 and connect the option to the RJ45 connector, the
communication between the inverter and the option is disabled, so the communication loss may be
detected.

3.4. Selection of the communication protocol (f829)

Set the communication protocol f829 to "4:BACnet protocol". The communication protocol of RJ45 is
set to MODBUS, so when communicate with PC, use MODBUS protocol.

3.5. Number of motor poles for communication (f856)

Set the motor pole number of using. This parameter is for the calculation of min-1 unit motor speed of
BACnet data.

3.6. Network address (f890)

Set the network address of this node. Do not set same address number in the segment, and not set over
MaxMaster (f895). If set wrong number, the option board does not work properly.

3.7. Network baud rate (f891)

Set the network baud rate to f891. Set the same baud rate data in the network. If set AUTO baud rate,
when the option detect network baud rate, the option sets the baud rate data to f891 automatically.

3.8. Instance Number (f893, f894)

Set BACnet Object Instance number. The instance number should not be duplicate in the network. The
instance number is 22bit data length, and set the number of this option board as below.
Instance number = f893 x 1000 + f894

3.9. MaxMaster (f895)

Set the max master number of this segment. The network poles to MaxMaster address to find master
node, so set MaxMaster to be small number to be a small response time.

3.10. MaxInfoFrames (f896)

Set the max information frame number to send from this node. Not need to change.
