All the devices on the network should be well earthed using their corresponding earthing terminals. As always, the earthing wires should not form any closed loops, and all the devices should be earthed to a common earth. The RS485 network must be terminated using 120 Ω resistors at both ends of the network as shown in Figure 9. These resistors are already resident on the adapter. Use jumpers S2 and S3 to connect the termination resistors. Figure 9 Termination for the RS485 link. The connections may only be made with the drive disconnected from the power source.

For details, see the ACS 140 Programming Guide. General When the ACS 100 - PAN control panel is attached to the drive, the panel communicates using the Modbus protocol and the settings given in Table 2. When power is connected, the ACS 140 will automatically check for the presence of the panel. If the panel is detected, the ACS 140 will set up the Modbus communication using the default settings shown in Table 2. Thissettings of the ACS 140 can be
