5.1.11 RS-485 Bus Connection
One or more frequency converters can be connected to a
controller (or master) using the RS-485 standard 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 frequency converter is connected to a
master, use parallel connections.
RS 232
USB
RS 485
Illustration 5.18 Connection Example.
To avoid potential equalising currents in the screen,
ground the cable screen via terminal 61, which is
connected to the frame via an RC-link.
Bus termination
Terminate the RS-485 bus by a resistor network at both
ends. If the frequency converter is the first or the last
device in the RS-485 loop, set the switch S801 on the
control card for ON.
For more information, see the paragraph Switches S201,
S202, and S801.
5.1.12 How to Connect a PC to the
Frequency Converter
To control or program the frequency converter from a PC,
install the PC-based configuration tool MCT 10 Set-up
Software.
The PC is connected via a standard (host/device) USB
cable, or via the RS-485 interface as shown in
chapter 5.1.11 RS-485 Bus Connection.
NOTICE
The USB connection is galvanically isolated from the
supply voltage (PELV) and other high-voltage terminals.
The USB connection is connected to protective earth.
Use only an isolated laptop as PC connection to the USB
connector on the frequency converter.
