How do you know if you have HAEN motors

[FastFieros]

I want to start thinking about changing the Fanuc 0M-A controller I have on my mill to a PC based CNC controller..

Can someone tell me how you order the 'right' parts the first time for this change over?

I know there are a few companies that sell package deals and offer to provide alot of tech support, but I want to either at least understand that I cannot do this on my own and need to order a complete turnkey solution, or piece the parts my self and install them. I can do both if I can understand all the terminlogy needed to get the right parts.

One thing I have found little information on is the interconnect to the servo motors. It easy to see alot of people are using a Galil PCI or ISA interface card. Then this has a 100 pin SCSI cable to a interconnect board.

I have seen the 1900 with AMP support, or no amp support.. I have seen the 2900 as recommended to go on this setup most common. However these interconnects are either LAEN ( low amp enble ) or HAEN ( High amp enable ).. I dont see how to know this reading the tag on my motor.

My servo motors are General Numeric DC brush type motors. The encoders are in the rear, but they are not the red, or yellow, or any other color I have seen on other machines.

Here is a picture of the tag on the motors attached.

How do I get some idea how to connect the servo motors to the interconnect? I have taken the connectors apart on the encoders, and there are about 7-9 wires inside solder to the pins.

The middle of the motor is a junction box with 5 wires. 2 are black and white. They are about 10 ga wire, so I know these are the voltage drive wires. Then there is 2 small wires about 24 ga, that I am guessing is a brake wire setup, then the other for sure is a chassis ground.

thanks for any help...

They might be badged GN,but these are Siemens HU motors.I`ve seen hundreds of them,the plate is unmistakeably Siemens and the part numbers are Siemens.
As regards retrofitting,exchanging a Fanuc OT for a mixture of bits and pieces seems a bit of a backward step when all that is wrong with it is an axis drive fault.
Get the axis drive repaired and have a machine that is industry standard,has spares and service available,can be programmed by nearly anyone with a bit Fanuc experience,has documentation for the control and drives and has a resale value.

I still want to try and fix the seimens controller, but it being a Fanuc 0M-A is so limited. If it was a C model to except DNC or had more memory, that would be great...

However, I would be able to at least cut out my motor plates still as these are only a 2D cut and drill.

I appreicate your help Mark in the other thread. I will look at the DC link voltage right now and respond in that thread in a little while.

If you are going to change from a a OM-A to a Galil card what are you going to use for software to run the galil card?

Standard config of the 1900 interface board amp enable is TTL active high. To change to active low you replace the socketed 7407 with a 7406. You can also jumper it for 12 volt signal rather than the standard TTL level. Instructions are in the Galil card manual.

Well, I see software options as MAch3, or CamSoft.... Galil seems to have some simple software interface, and I can actually poke around in VB6 enough to build a front end if I get the WSDK package.

As to the 1900 interconnect, I had found the info on Galil site that you can configure it for LAEN or HAEN... if it amounts to changing the 740X chip, I can do that also. Maybe it is socketed no... that would be easy...

[CarbideBob]

On my 1100 interconnect board it is socketed. Never had to change it on on my 1900s so I'm not sure.

From the posts I've seen here there seems to be some problems using Mach.
Camsoft is not cheap but probably the easiest way to do it.

Yes you can use the Galil libraries to interface to VB6 but a full cnc controller is not what you would call simple software. By the time you implement things like cutter comp, backlash comp, and all the other features of an OM-A things get pretty involved.
It certainly can be done though. I wrote my own in VB6 (with a little bit of C thrown in). It emulates the functionality of a Fanuc 10M controller plus a few bells and whistles. Currently about 20,000 lines of VB6 code and still growing.

The LAEN & HAEN do not refer to the motors but apply to the drives and how they are enabled.
If you intend retrofitting then I would recommend obtaining PWM drive and use them in the Torque mode of operation, this means you can do away with the motor Tach or just remove the brushes.
Make sure they are encoders and not resolvers.
The two 24 gauge wires could be either the tach or the motor temperature sensor.
