RS-485 Bus Connection
A frequency converter or active filter can be connected to
a controller (or master) together with other loads 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-).
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 or active filter is the first
or the last device in the RS-485 loop, set the switch S801
on the control card for ON.
5.1.11
Connection to a PC
To program the unit 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
to the unit, or via the RS-485 interface.
NOTICE
The USB connection is galvanically isolated from the
supply voltage (PELV) and other high-voltage terminals.
The USB connection is connected to protection earth on
the unit. Use only an isolated laptop as PC connection to
the USB connector.
For control cable connections, see chapter 3.4.20 Electrical
Installation, Control Cables.
