Chapter 4 Explanation of Functions The commands are described below. (i) 00 command: This command instructs the inverter to drive the motor (for forward or reverse rotation) or stop the motor. (To use this command, set "A002" to "03" [RS485].) - Transmission frame Frame format STX Station No. Command Data BCC CR Description Data size Setting STX Control code (Start of TeXt) 1 byte STX (0x02) Station No. Station number of control-target inverter 2 bytes 01 to 32, or FF (broadcast to all stations) Command Command to be transmitted 2 bytes 00 Data Data to be transmitted 1 byte See Note 1. BCC Block check code 2 bytes XOR of the items from "Station No." to "Data." See Item (3) of this section. CR Control code (Carriage Return) 1 byte CR (0x0D) Note 1: Data Description Remarks 0 Stop command 1 Forward rotation command 2 Reverse rotation command (Example) When sending a forward rotation command to the inverter with station No. 01: (STX) |01|00|1| (BCC) | (CR) Conversion into ASCII format 02|30 31|30 30|31|33 30|0D - Response frame Positive response: See Item (2)-(i) of this section. Negative response: See Item (2)-(ii) of this section. (ii) 01 command: This command sets the inverter output frequency. (To use this command, set "A001" to "03" [RS485].) - Transmission frame Frame format STX Station No. Command Data BCC CR Description Data size Setting STX Control code (Start of TeXt) 1 byte STX (0x02) Station No. Station number of control-target inverter 2 bytes 01 to 32, or FF (broadcast to all stations) Command Command to be transmitted 2 bytes 01 Data Data to be sent (decimal ASCII code) 6 bytes See Note 2. BCC Block check code 2 bytes XOR of the items from "Station No." to "Data." See Item (3) of this section. CR Control code (Carriage Return) 1 byte CR (0x0D) Note 2: For example, to set the output frequency of the inverter with station No. 01 to 5 Hz, the data is as follows: (STX) |01|01|000500| (BCC) | (CR) Conversion into ASCII format 02|30 31|30 31|30 30 30 35 30 30|30 35|0D Note 3: The data indicates a value 100 times as large as the actual frequency value to be set. (Example) 5 (Hz) → 500 → 000500 Conversion into ASCII format 30 30 30 35 30 30 Note 4: When using the data as the feedback data for PID control, set the most-significant byte to "1". (Example) 5 (%) → 500 → 100500 Conversion into ASCII format 31 30 30 35 30 30 - Response frame Positive response: See Item (2)-(i) of this section. Negative response: See Item (2)-(ii) of this section. 4 - 118

Chapter 4 Explanation of Functions (iii) 02, 12 command: This command turns the specified intelligent input terminals on or off. - Transmission frame Frame format STX Station No. Command Data BCC CR Description Data size Setting STX Control code (Start of TeXt) 1 byte STX (0x02) Station No. Station number of control-target inverter 2 bytes 01 to 32, or FF (broadcast to all stations) Command Command to be transmitted 2 bytes 02 Data Data to be transmitted 16 bytes See Note 5. BCC Block check code 2 bytes XOR of the items from "Station No." to "Data." See Item (3) of this section. CR Control code (Carriage Return) 1 byte CR (0x0D) Note 5: The table below lists the functions of the intelligent input terminals and corresponding hexadecimal data.
