Motoman and Fronius

[Kt33]

 :help:I have a Motoman NX and a Fronius. The Arc off signal is not working correctly. Aren't there any Macro Jobs from Motoman for the Fronius?

What does it mean ??

The Arc off signal is not working correctly.

More details!

I've worked with fronius and Motoman MRC... It worked perfectly... And I'm sure that the Motoman NX can communicate with fronius too...

what is exactly your problem?  Can't you create the jobs in the machine? Can't the robot open the arc? Does it show a error message when you start the arc command?

Rsy, how did you configure the I/O of the Fronius machine with the MRC controller. I ask this because the analog control of the fronius machine uses volts and wire speed, and the mrc uses current and voltage. Also how did configure the digital signal for to comply with the machine work diagram.

Thank You For Your Attention.

How are you operating the fronius ? .....the only command from robot is ARCOF the power source controls the  the arc end.....so if you are using arc ending files.....you may be doing more than you need...

[Ed_Gein67]

My main problem relates to analog outputs. The Fronius machine has 2 analogs for Voltage and Wire Speed, and the mrc has outputs for voltage and current. For the start stop welding, I think I have it covered.

Thank You For Your Attention.

I can't remember that long ago....but seems I set scaling to be WPS but my weld files displayed AMPS......

Gidday, not sure if this is what your after ,however it might help with your understanding.
Motoman welder control cards have two analog out puts 0>14.6v along with switched outputs, weld on etc.
they are called voltage and current - Current IS wire speed . Left over from the old
Mig/mag welders of old , Millers & Lincoln  still have wire speed on their wire feeders ,not sure
if they still do on newer Digital welders.
These two analog outputs are to be treated carefully as they are comoned  Opto couplers within the board. If you have different supply for wire feeder as against welder you can have fault that will destroy one or both Opto couplers , Millers is a good example wire feeder is stand alone & the Power supply is different again , in this case you need to fit a PID to one of the analog outputs to isolate them. , fitting 1004IN diodes to the + output wires is a good idea , just remember that you lose .5v. These blocking diodes protect the 2x Opto couplers from a number of welder  faults.
Another means of controlling some of the newer Welders is by setting blocks of outputs to binary numbers , with these in turn selecting pre-arranged or set welding files within the welder itself, several of the lastest German machines are like this.

Thank you all for your replies. What I am doing is turning a MRC that had sks welding machines with I/O interface UNI 4, into a MRC with a Fronius machine with I/O interface ROB5000. This transition is supposed to happen without changing the way it was working. The Client wants to able to change internal parameters on the machine and fine tune with the analog outputs.

Thank You For Your Attention.
