The following is a quick reference guide for serial communications to the F7 drive. Make a copy of this page and check-off each item as it is
completed. For detailed information please refer to the detailed sections that follow.
1: RS232 communication
1.1: Verify that the correct cable is used to connect the controller to the F7 drive.
1.2: Verify that the controller is set for RS232 communications and that the communications’ cable is connected to the
correct communications port.
1.3: Record the controller communications’ parameters

1.5: Verify that the communications’ parameters match.
2: RS422/RS485 communications.
2.1: Verify that the F7 drive is connected correctly.
2.2: Verify that the controller is set for RS422/RS485 communications and that the communications’ cable is connected to
the correct communications’ port.
2.3: Record the controller communications’ parameters

2.5: Verify that the communications’ parameters match.
2.6: Verify that parameter H5-07 (RTS) is set to enable.
2.7: Verify that parameter H5-01 (Node Address) is set to the correct, unique, hexadecimal value and that it matches the
node address required by the controller.
