Converting Haas Bar Feeder CHC to NGC

Introduction

This procedure will show you how to convert a Haas Bar feeder that was configured to run on a Classic Haas Control to a Next Generation Control (NGC). This kit also includes an adapter P/N 33-5712A that will allow you to connect the Haas Bar feeder back to a Classic Haas Control. The installation of this adapter will be covered in the Haas Bar Feeder - Installation - CHC procedure.

Follow the Haas Bar Feeder NGC - Installation procedure below after converting the Haas Bar Feeder.

Haas Bar Feeder NGC - Installation

This procedure applies to the following kit:

93-3500 CF To NGC Haas Bar Feeder Kit

CHC Parts Removal

Remove the 32-7464 CBL200 END OF BAR PHOTO SENSOR N.C. photo sensor [1].
Note: If the Bar feeder is installed to a Classic Haas Control machine disconnect the cable P/N 32-7464 at I/O PCB P35 and PSUB PCB P13 .

Remove the 25-11030 BRKT BAR MEAS SW BARFEED photo sensor bracket [2].

Remove the 69-1734 N.C. LOAD “Q” proximity switch [4]

Remove the 69-1733 N.O. LOAD BAR proximity switch [5]

Remove the 69-1733 N.O. DOOR SW proximity switch [3].

Remove the 69-1733 N.O. PUSHED OUT proximity switch [6] mounted in lower part of the bar feeder.

Remove cables p/n 33-2018 and 33-2016 from the bar feeder.
Note: If the Bar feeder is installed to a Classic Haas Control machine disconnect the cables P/N 33-2016 at I/O PCB P21 and cable p/n 32-2018 at I/O PCB P24 .

NGC Parts Installation

1

Install the end of bar bracket p/n: 25-11030A END OF BAR SW BRKT BARFEED.

Install the end of bar photo sensor p/n: 32-7465 CBL200 END OF BAR SENS 12V.

Install the proximity switches cable p/n: 32-5715 N.O. PUSHED OUT, N.O. DOOR SW, N.C. LOAD “Q” and N.O. LOAD BAR to their correct location.

Insert the cables inside the conduit and follow the same cable routing as the previous configuration.

The NGC control uses parameter 13.78 instead of 415 for the V-axis Tool Change Offset. The NGC control uses millimeter values for parameter 13.78 V-Axis Tool Change Offset instead of encoder steps. It is necessary to convert the Classic Haas Control Parameter 415 V-Axis Tool Change Offset value to millimeters.

On the back of the Bar Feeder locate the "Haas Bar Feeder Parameter" decal (29-0987).

Write down the number listed in the decal for parameter 415. Divide this number by 44390. Convert the results to millimeter.

Example: 77461 / 44390 = 1.7450

1.7450 x 25.4 = 44.323 (MM)

Remove the old decal and install decal 29-0987A DECAL PARAMETERS HAAS BAR FEEDER.

Use a permanent marker to write down the value of NGC parameter 13.078. This value will be needed during installation.

Install the Bar Feeder:

NGC Lathe, Refer to Haas Bar Feeder - Installation - NGC
CHC Lathe, Refer to Haas Bar Feeder - Installation - CHC

Servo Motor Cable Upgrade

The Haas Bar feeder servo motor cable has been upgraded to a braided style. Complete this section only if the Haas Bar Feeder was built before April, 2017 and it will be connected to a NGC machine.

Locate the Servo Motor.

Disconnect the encoder cable [1] from the motor. Disconnect the cable going to the home sensor [3].

Disconnect the Motor power cable [2] from the motor.

Install the updated encoder/home sensor cable p/n: 32-0484.

Install the updated motor power cable p/n: 32-1650.

Note: The updated motor power cable p/n: 32-1650 will require a ferrite filter p/n: 64-1252 installed at the amplifier side when installing the bar feeder to an NGC Lathe..
