Installation Of Misc. Connections - GE AF-600 FP Design Manual

4.5 Installation of Misc. Connections

4.5.1 RS 485 Bus Connection
One or more frequency converters can be connected to a control (or master)
using the RS485 standardized 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
4 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
The RS485 bus must be terminated by a resistor network at both ends. For this purpose, set switch S801 on the control card for "ON".
For more information, see the paragraph Switches S201, S202, and S801.
4.5.2 How to Connect a PC to the Frequency Converter
To control or program the frequency converter 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 AF-600 FP Design Guide, chapter How to Install > Installation
of misc. connections.
NB!
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 frequency converter.
Illustration 4.20: For control cable connections, see section on Control Terminals.
PC-based Configuration Tool DCT 10
All drives are equipped with a serial communication port. We provide a PC tool for communication between PC and frequency converter, PC-based Configuration
Tool DCT 10.
