Dynapath problem

[rr167]

I have a Lagun mill w/ Dynapath 20 control.
Machine rapids to Z axis clearance and stops at that point. If I enable z axis inhibit it runs fine ( with z movement)
Any clues?

This sounds like an In-Position problem. To check this, run your program and when it stops look to see if the asterisk next to the Z axis readout turns on. If not, the control is waiting for the axis to be in-position.

To adjust:
Go to the Setup Mode and turn on TM4 (lag display). Go to the Jog mode and look at the lag display for the Z axis while jogging it up and down in Medium feed. Note the amount of lag as it jogs in both directions, these values should be the same (but opposite sign). If these numbers are significantly different, your Z axis offset needs to adjusted on the drive. Tweak the drive's offset pot until these numbers are the same in both directions. After this is done, the lag should be less than 0.0005" when the axis is sitting still. If it's not, you may also need to adjust the drive's gain.

Hope this helps,
Scott

Hey all,

First time posting. I have been donated an Excello knee mill equipped with a Dynapath 10 controller. Unfortunatly when the machine was being moved it must have affected the axis lag on the X Y and Z axis. They are all floating at about .003-.006. Is there any documentation that could show me how to adjust these? I have no manual for the controller itself only a programing book. Any help would be great.

Cheers
