General Mach Discussion / Yapsc to Fanuc amplifier Has anybody done it ????

« on: May 18, 2011, 05:39:36 AM »

Hello guys,

I am interested using YAPSC:10 to a retrofit a Fanuc system.
My Fanuc is Amplifier-Motor system with analogue inputs.

Can I use YAPSC:10 or other with Fanuc Velocity control unit A06B-6050-H404 and motor A06B-0501-B002?

I  send schematics of the connections.

Best Regards,

Thank Ian 

Simple issues are most difficult.

Hello there,

I just want to energize a output and change pulley.

I am new to this and i have tried several scripts but nothing.
The following is giving a '' Scriper Compile Error. In SpindleSpeed.mis''


rpm = GetRPM()
If
RPM > 2501
Then
SetPulley(2)
ActivateSignal(OUTPUT5)
End If

If
RPM < 2501
Then
SetPulley(1)
DeActivateSignal(OUTPUT5)

End If
SetSpinSpeed( rpm ) 


What is going on?

Yes is senssorless drive.
The physical belt-pulley system in changed through a solenoid valve.

Today I study my problem and I saw that BOB output range is completed form S0 to S200 rpms!!!
I have disconnect everything tried different settings for pulleys form max 2500 to 25000 but the same output.
I have disable the motor X,Y,Z , I have only 10V from VFD to BOB.
Steps are set to 1000 and Velocity to 1500 with a 25000KHz kernel.
I used different Steps and Velocity setting but always full range is from S0 to S200...

Hello guys,

I need to change pulleys under Mach3 when commanded a specified S*****.

Has any body done this?

General Mach Discussion / Spindle problem need help

« on: September 01, 2010, 03:31:46 AM »

Hello guys,

 I trying to retrofit a Fadal 4020 machine to mach3 but I am troubled by the spindle-pulley settings.
I use a C11G board and the machine has 2 pulleys. 1 is for 0-2500 and 2 is for 2500-10000.
Tunning this is hell, I use only pulley 1 to tune the VF output but either I have full speed or minimum.
Motor is a Baldor with 1750rpm at 60Hz.

Any ideas??

Thanks in advance.

General Mach Discussion / Wired calibration problems

« on: August 23, 2010, 08:21:32 AM »

Hello to all.

First time I am posting to this forum but I have found a lot of useful posts here.
I have upgrade a Fadal machine with Glentek GM4050 motor (see picture below).
Using Mach3 and CNC4PC board C11G with SCANCON encoder 2R-2000.
MX2 omron spindle drive connected in the VF input.
I have two problems.
 1) Spindle calibration is impossible. I have in Mach3 very big oscillations in the graph.
The spindle is running at full speed because the output from the board does not change at any S****.
So I believe it is a Mach3 configuration problem.
 2) I am trying to use macropupms combine with some inputs but:
    I see that the macro is energizing the function with the real input.
And I see that input are flashing periodically !!
Any ideas why this happens.
 3) I am facing a strange problem X axes although in other axes everything works fine.
I have loosened the table’s gibs so I don’t have any mechanical influence.
I tunning the motor in all possible settings but no fix.
I am moving the axes by 1mm  in forward direction and everything is OK. But when I reverse it I have a counter loss but not in the first 2-3mm after this the loss is getting bigger and bigger by millimeter.
I also tried to move 300mm forward and reverse, the loss is bigger than 10mm.
Do you have any idea what could be the cause?

Thank you in advance guys
