Network Cable Connection

Follow the instructions below to connect the drive to a MEMOBUS/Modbus network.
1.
With the power shut off, connect the communications cable to the drive and the master. Use the terminals shown in
the figure below for network cable connections.
Note: Separate the communications cables from the main circuit cables and other wiring and power cables. Use shielded cables for
the communications cables, and properly shielded clamps to prevent problems with noise. When using RS-485
communications, connect S+ to R+, and S- to R- as shown in the diagram below.
2.
Check or set the terminating resistance at all slaves. Use the description in
1000 series drives.
3.
Switch the power on.
4.
Set the parameters needed for serial communications (H5-01 through H5-12) using the LED operator.
5.
Shut the power off and wait until the display on the LED operator goes out completely.
6.
Turn the power back on.
7.
The drive is now ready to begin communicating with the master.
