Figure 6. Connection diagram
The figure shows a typical arrangement with a host
computer (master) and any number maximum 31 slaves
of frequency inverters. Each frequency inverter has a
unique address in the network. This addressing is executed
individually for each AFD via the communication parameters.
The electrical connection between master and the slaves
connected in parallel are implemented via the serial
interface A-B (A = negative, B = positive) with a shielded
RS-485 twisted pair cable.
