Goodrive300 Series VFD Extension card

● Insert the module into the defined location carefully and fix it on the copper column with screw.
● Set the bus terminal switch of the module to the needed location.
3. Notes:
Disconnect the device from the power line before installation. Wait for at least three minutes to let the
capacitors discharge. Cut off dangerous voltage from external control circuit to the unit output and
input terminals.
Some electric components are sensitive to static charge. Do not touch the circuit board. If you have to
operate on it, please wear the grounding wrist belt.
A.2.6.2 Electrical installation of EC-TX-103 communication card
1. Node selection
Node address is the only address of PROFIBUS on the bus. The address which is among 00–99 is
shown with two figures and is selected by the spinning switch on the module. The left switch shows
the first number and the right one show the second number.
Node address = 10 x the first digital value + the second digital value x 1
2. Bus terminals
There is a bus terminal in each heading and ending to avoid error during operation. The DIP switch on
RPBA-01PCB is used to connect the bus terminals which can avoid the signal feedback from the bus
cables. If the module is the first or last one in the internet, the bus terminal should be set as ON.
Please disconnect EC-TX-103 communication card terminals when the PROFIBUS D-sub connector
with internal terminals is in use.

A.2.6.3 Bus net connection of EC-TX-103 communication card
1. Bus communication interface
Transformation by double-shielded twisted pair copper cable is the most common way in PROFIBUS
(conform to RS-485standard).
The basic characteristics of transformation technology:
● Net topology: Linear bus, there are bus resistor in two ends.
● Transforming speed: 9.6k bit/s–12M bit/s
● Medium: double-shielded twisted pair cables,the shield can be removed according to the
environment (EMC).
