Page 23 Host computer Block 1 Inverter No. 10 Inverter No.11 Inverter No.19 VF-AS1 VF-AS1 VF-AS1 In broadcast communication, only the representative inverter in each block returns data to the host computer. This is because there will be a risk that the returned data may be deformed. At time of broadcast communication of the binary mode, returning of data is not executed except for the inverter to be returned (inverter number 00H) and when the inverter number is not matched. Page 15 Block Write 1, 2 Select data, which is desired to be written in block communication, in block write Data 1 and 2 Pa- rameters (, ). Page 16 Inverter → Computer At time of broadcast communication of the binary mode, returning of data is not executed except for the inverter to be returned (inverter number 00H) and when the inverter number is not matched. There are other implementations of RS485 networks where every node can start a data session on its own. Modbus devices communicate using a Master-Slave technique where only one device (the Master) can initiate transactions (AKA queries). Page 20 When Command "s" (lowercase letter) is received, the slave side judges that the master side is tripped and operates in accordance with the inter-drive communication parameter (, ).

4.5. Examples of the use of communication commands Here are some examples of the use of communication commands provided for the VF-AS1 series of inverters. Although many applications use RS-485 signal levels, the speed, format, and protocol of the data transmission are not specified by RS-485. A mode fault occurs when the SPI senses that a multimaster conflict (MC68HC11F1 Technical Data Manual, p.10-5) exists on the network as explained above in connection with the /SS input. Page 10 • Data returned when data is not processed normally (ASCII mode) In case an error occurs, communication error command (4EH(N) or 6EH(n)) and the error type num- ber is returned to the computer in addition to the checksum. It writes data into the RAM only. Page 19 P (50 (RAM write) This command is used to rewrite data into the parameter specified using a communication number. Now in the loop, we check if there is anything available on the serial port and then read the data and since the incoming data is an integer, we parse it and display on the connected LCD. Sometimes you can read from some register that has a known value.


Vehicle mounted camera solution can be deployed where a rapid security response is required. Appendix 2 Response time The communication response time can be calculated from data communication time and inverter processing time. When using the TOSHIBA inverter protocol and the data does not need to be records, use P command (the data is written only to RAM). There are two communication protocols available: Toshiba Inverter Protocol and MODBUS-RTU Protocol (this command does not support all commands). ) is set for initial communication protocol selection of shipment setting. 3. Communication protocol This communication protocol supports the TOSHIBA Inverter Protocol and part of MODBUS-RTU protocol. Page 48 Frequency setting from the computer Setting range: 0 to maximum frequency (fh) This frequency command is enabled only when the frequency command by communication is en- abled. Page 13 2) Error Processing (Binary mode) In case an error occurs, communication error command (4EH(N) or 6EH(n)) and the error type num- ber is returned to the computer in addition to the checksum. 4.1.2. Data transmission format used in binary mode A communication number is used to specify a data item, data is written in hexadecimal form, and data in transmission characters are represented by binary codes (HEX codes).


4.1.1. Data transmission format used in ASCII mode A communication number is used to specify a data item, all data is written in hexadecimal, and JIS- X-0201 (ASCII (ANSI))-compliant transmission characters are used. Each time an attempt to write data is made the inverter checks whether the data falls within the specified range. If you are running Serial2 at 4800 baud, the rest of your application must be able to function properly using the remaining portion of the CPU time. EEPROM is approximately 10,000 times.(Some parameters are not limited, please refer to the "9.Parameter data ") When using the TOSHIBA inverter protocol and the data does not need to be records, use P command (the data is written only to RAM). 4.1. Data transmission format Note: The term "trip status" used in this manual includes retry waiting status and trip retention status. 4.1.3. Transmission format of Block Communication What is block communication?
