Verify Communications
The following is a quick reference guide for serial communications to the E7 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.
RS232 communication
1:
Verify that the correct cable is used to connect the controller to the E7 drive.
1.1:
Verify that the controller is set for RS232 communications and that the communication's cable is connected to the
1.2:
correct communications port.
Record the controller communications' parameters
1.3:
Baud Rate
Record the E7 drive communications' parameters (H5-02, H5-03, H5-07, H5-08)
1.4:
Baud Rate
Verify that the communications' parameters match.
1.5:
RS422/RS485 communications.
2:
Verify that the E7 drive is connected correctly.
2.1:
Verify that the controller is set for RS422/RS485 communications and that the communication's cable is connected to
2.2:
the correct communications' port.
Record the controller communications' parameters
2.3:
Baud Rate
Record the E7 drive communications' parameters (H5-01, H5-02, H5-03, H5-07, H5-08)
2.4:
Baud Rate
Verify that the communications' parameters match.
2.5:
Verify that parameter H5-07 (RTS) is set to enable.
2.6:
Verify that parameter H5-01 (Node Address) is set to the correct, unique, hexadecimal value and that it matches the
2.7:
node address required by the controller.
