VB and the development of wizards / Cypress error

« on: May 06, 2011, 04:14:19 AM »

While adjusting some servo drive settings and we would restsart Mach and when running the Home routines the attached message would appear and  system would error out.

After a reboot and restart it would behave correctly.

This is a new installation this year running on a license and been performing correctly for nearly a month.  Till to that is!!.

Any ideas as to why??

Screen dump of error is attached.

dspMC/IP Motion Controller / Problem with the Z axis.

« on: January 25, 2011, 11:32:52 PM »

Hi,
I hope you can shed some light on the last (known) problem on our router retrofit using Mach and the 7762M  Vital motion control box.

The Z axis is unreliable. it will run at up to about 700mm/min apparently reliably. The X Y and B (Tool Changer) are all workin fine.

With the Feed in exceess of this it will start then run at a much faster speed apparently for ever. Of course the Z axis travel is only 300mm so we quickly hit the stops.

It happens if the move is +ve or -ve direction.

We have been unable to improve this behavious except by running at very low speed.

It is not the drive or servo as we have swapped in replacements which did not elininate the problem.

Likewise we have eliminated the connector cable betwee the Vital systems box and the drive.


Our impression is that it is either Mach instructing the 7762 or the 7762 making a velocity output in excess of reasonable.

The position DRO's indicate normal and do not reflect the increased speed.

The servos and drives are FUJI and the operating system on the PC is XP

Currently we are stumped and would appreciate any comments and assistance

Thanks

dspMC/IP Motion Controller / How to reverse servo's in Mach or DSPMC software

« on: January 25, 2011, 02:37:39 AM »

Hi,
Please advise how to reverse the servo directions in a MACH/DSPMC setup.

Changing the dir in PORTS and PINS in motor setup does not have any effect.

General Mach Discussion / hickup at 12 and 6 oclock

« on: April 18, 2007, 05:04:48 PM »

Hi
We are developing a new machine and part of it is an XY table moving in a circular motion.

Using code listed below.

At 12 and 6 oclock on the graphics we can see a disturbance on the feedrate DRO. This shows in the servo motion as a blip and spoils the smooth motion we need.

I have tried faster PC's = makes no difference
Slowed feed speed down to 100mm/min - still present

It would appear as if at the point of calculating the G03 the pulse output gets disturbed

We are using version .062

Can you provide any ideas as to how to avoid this issue

Regards

Graham
