5.1.11 RS-485 Bus Connection
One or more adjustable frequency drives can be connected
to a controller (or master) using the standard RS-485
interface. Terminal 68 is connected to the P signal (TX+, RX
+), while terminal 69 is connected to the N signal (TX-,RX-).
If more than one adjustable frequency drive is connected
to a master, use parallel connections.

In order to avoid potential equalizing currents in the
shield, ground the cable shield via terminal 61, which is
connected to the frame via an RC link.
Bus termination
The RS-485 bus must be terminated by a resistor network
at both ends. If the drive is the first or the last device in
the RS-485 loop, set the switch S801 on the control card to
ON.

Switches S201,
S202, and S801

5.1.12 How to Connect a PC to the
Adjustable Frequency Drive
To control or program the adjustable frequency drive from a PC, install the PC-based Drive Control Tool DCT 10.
The PC is connected via a standard (host/device) USB cable, or via the RS-485 interface as shown in the
Design Guide,
chapter How to Install > Installation of misc. connections
.
NOTE!
The USB connection is galvanically isolated from the
supply voltage (PELV) and other high-voltage terminals.
The USB connection is connected to protection ground on
the adjustable frequency drive. Use only an isolated laptop
as PC connection to the USB connector on the adjustable
frequency drive.
