In G-code,
G4 (or G04) = Dwell
P = Period of dwell, when used after G4 (P can have other meanings depening on context)

G4P60 = Dwell for 60 seconds (unless you have changed it to millisecond (Config/Logic, middle column, check box for milliseconds))

You can try this for a test:

F1000 (i.e. faster than possible but Mach3 will limit speed)
G20 G90 (Inch and Absolute)
M98 P1234 L50 (run subroutine 50 times)
M30 (stop)
O1234
G1 X4
G4P2 (stop for 2 seconds)
G1 X0 (do a feed rate move and move back)
M99 (return)

You can also try Config > State:


....but I don't think this will make a difference for that simple program.

Osman, your application of Mach3 with a VFD is very unusual, and I think your best help will come from the Mach forums at:

http://www.machsupport.com/forum/index.php

and

Your Omron controller is actually produced by Yaskawa:

dear all
thanks for your help and I'm sorry for long time to contact you but rely I'm busy to adjust my machine with this type of inverter . it isn't easy but by the the end and after long fitting today i just finish to adjust x axis and I'm rely succeed 100 % INSHAA' ALLAH
as i told u before now it's work as servo but to reach this that's very important point
1- make motor tuning to adjust motor with encoder and inverter and this tuning should be running tuning
2-adjust pg parmeter
3- adjuster ASR parmeter to adjust feedback from encoder
4-use mode v/f with pg feedback
5- adjust v/f curve and parmeter
thanks for all

Mabruk! Thanks for the feedback.

I would really like to see some pictures (or even a video?) of that big machine.

Have a look at this long thread: Limit Switches - optical / mechanical / proximity There we have a long discussion about different types of switches and how to use them with Mach3. However, we conclude that proximity switches are the best (for dirt and accuracy), but it is a little tricky to use them in series for Mach3. The trick is use a little electronics with the proximity switches, or even just use a simple small relay. In your case, with water and mud, the proximity switches should really be the best.
