3 INSTALLATION AND WIRING
3.1 Installing the Expansion I/O Board
Follow next steps in order to install the expansion I/O board 3G3AX-EIO21-RE:
1.-Before installing the expansion I/O board, power up the inverter.
2.-Set inverter parameter C091-Debug Mode = 1.
3.-Set parameter P199 = 1.(*)
4.-Power down the inverter and wait at least five minutes before moving to the next step.
5.-Open and remove the lower terminal cover and confirm that the red CHARGE LED is extinguished
and that the DC bus is fully discharged before proceeding further, otherwise there is the danger of
electric shock.
6.-Then remove keypad from inverter. You can now remove the upper front cover to expose the two
option ports inside.
7.-Next figure shows how to install the option board to option port 1 or 2 of the inverter. There are four
holes on the corners of the option board. Align the board with the port connection in the proper
orientation (to the left, when facing the inverter as show). Then align the top two holes with the two
screw holes, and the bottom two holes with the two guide posts. Insert the board fully into the
connector. Secure the board with the two screws supplied.
8.-Then wire expansion I/O board 3G3AX-EIO21-RE. Wiring example:
9.- Power up the inverter. Confirm in the expansion I/O board that the RUN and PWR leds are
activated. It will indicate expansion I/O board is working.
10.- Program with CX-Drive and Drive Programming tool your program using the exclusively
dedicated user parameters for your application purpose.
11.- Set the inverter parameter A017 to value 1 or 2 to run the Drive Programming program. Now,
Drive Prorgamming program is linked and working with the expansion I/O module 3G3AX-EIO21-RE.
(*) All new option boards will not work with this new setting (Profibus, devicenet, componet, ethercat).
