    G7 drive to be completely discharged. Measure the DC bus voltage and verify that it is at a safe level. 4: Connect the G7 drive to an RS-232 network. Note: It is not possible to use the drive’s keypad and an RS-232 connection at the same time.
  • Page 9: Verify Operation

    Refer to the G7 drive Technical Manual for information on connecting and operating the G7 drive. Remove power from the G7 drive and wait for the charge lamp to be completely extinguished. Wait at least five additional minutes for the G7 drive to be completely discharged.

  • Page 11: Network Connections

    The RS-232 network is a single ended network with limited data transmission rates and cable lengths. The G7 drive RS-232 data transmission is fixed at 9600bps, no parity, 8 data bits and 1 stop bit. The maximum cable length is 50 ft (16 m). It is recommended that Yaskawa cable UWR00468-2 be used.
  • Page 12 RS-485 2-Wire Network RS-485 2-wire networks can be either single or multi-drop networks, with each slave device on the network assigned a unique node address. A maximum of 31 devices may reside on any network segment before a repeater is required. The maximum segment length is 4000 ft (1200 m). Set the Termination Resistor S1 switch to ON (slide the switch to the right) on the last device on the network.
  • Page 13: Communications Parameters

    Node Address – H5-01. The node address is set through G7 drive parameter H5-01. When communicating via RS-422 or RS-485, a unique node address between 0 and 20h (32 decimal), inclusive, must be entered. The default G7 drive address is 1Fh (31 decimal).
  • Page 14 B1-01 or B1-02 must also be set to a 2 (Serial Communication) for fault monitoring to occur. If the CE fault is enabled, the G7 will flash CALL on the keypad after power up until a message is received. The drive will trip and respond according to H5-04 if communication is lost (a message is not received) for more than 2 seconds after successful communication has been initiated.
  • Page 15: Run/Stop And Frequency Reference Source

    Run/Stop and Frequency Reference The Run/Stop and Frequency Reference commands can originate from: Serial communication (Built-in Modbus: Keypad or R+/-, S+/- Terminals) Keypad (Digital Operator) Terminal Strip Option Card Parameter B1-01 (Run/Stop Method Selection) allows the selection of the origin of the Run/Stop command. Parameter B1-02 (Reference Selection) allows the selection of the origin of the Frequency Reference command.

  • Page 20: Protocol

    Yaskawa refers to as MEMOBUS. The G7 drive supports Modbus functions 3, 6, 8 and 10h. The message format varies depending upon the function code of the message. For each function code, there is a command message from the master and a response message from the slave. The following sections review the format of the command and response messages for each function.
  • Page 21: Read Multiple Registers - Function Code 03H

    Lower Each G7 drive slave address is set via parameter H5-01. Valid slave addresses must be in the range of 1 ~ 20 hex (1 ~ 32 dec) and entered as a hexadecimal number. No two slaves may have the same address. The master addresses the slave by placing the slave address in the Slave Address field of the message.

  • Page 29: No Response

    No Response The slave disregards the command message and does not return a response message in the following cases: In broadcasting of data (slave address is 0), all slaves execute, but do not respond. When a communication error (overrun, framing, parity, or CRC-16) is detected in the command message. When the slave address in the command message does not coincide with the address set in the slave.
  • Page 30: Crc-16 Calculations

    CRC-16 Calculation The last two bytes of a message contain the CRC-16 (Cyclical Redundancy Check). The CRC-16 is one method for verifying the validity of the message contents and is part of the protocol. The CRC-16 field checks the contents of the entire message, regardless of any parity check method used for the individual characters of the message.
