ADAP-KOOL Drive Operating Instructions
6.1.3 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-).
Illustration 6.1 Connection example.
If more than one frequency converter is connected to a
master, use parallel connections.
In order to avoid potential equalizing currents in the screen, earth the cable screen via terminal 61, which is connected to
the frame via an RC-link.
Bus termination
6 6
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 for ON.
For more information, see the paragraph Switches S201, S202, and S801.
6.1.4 How to Connect a PC to the AKD 102
To control or program the frequency converter from a PC, install the 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 the ADAP-KOOL Drive
AKD102 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 earth on the frequency converter. Use only isolated laptop as PC connection to the
®
USB connector on the ADAP-KOOL Drive.
6.1.5 PC Software Tools
PC-based Configuration Tool MCT 10
All Frequency converters are equipped with a serial communication port. Danfoss provides a PC tool for communication
between PC and frequency converter, PC-based Configuration Tool MCT 10. Please check the section on Available Literature
for detailed information on this tool.
MCT 10 Set-up Software
MCT 10 has been designed as an easy to use interactive tool for setting parameters in our frequency converters. .
The xMCT 10 Set-up software will be useful for:
