Important:
• Separate the communication cables from the main circuit cables and control circuit wiring.
• Use shielded cables for the communication cable, and use proper shield clamps.
• When using RS-485 2 Wire communication, connect S+ to R+, and S- to R-, on the control circuit terminal board. See
Figure 88. .
• Terminate shield at one end only.

◆ Procedure for Setting Up Communication
Use the following procedure to perform communication with the PLC.
1. Turn OFF the input power to the iQpump drive and connect the communication cable between the PLC and the drive.
2. Turn ON the input power to the drive.
3. Set the required communication parameters (H5-01 ~ H5-09) using the Digital Operator.
4. Turn OFF the input power to the drive, and check that the Digital Operator display has completely faded.
5. Turn ON the input power to the iQpump drive once again.
6. Perform communication with the PLC.
■ Related Parameters
The following parameters need to be set correctly to insure proper operation of the iQpump drive when using MEMOBUS / Modbus
