“.04" sec. Repeating the test, we find that it now takes 1 to 2 pulses to move .001 inch - an acceptable value.
Now it is time to hit the “AUTO ADJUST” softkey. The slide moves up past 14.000 (the slide setpoint we entered in the operation screen) and stops momentarily at 14.025. It then comes back down and stops at 13.996. The “Pulse Distance” value is set too high. What should have happened is that the slide would go over 14.000, come back down to a position just over 14.000 - say 14.003 - and then pulse into position at 14.000. Since we went under our setpoint by .004 inches, we change the “Pulse Distance” to
.017 inches (adding .004 for the undershoot plus .003 for good measure to the original value of .010). Now when we hit the “AUTO ADJUST” softkey the slide travels first to 14.039, stops momentarily, travels down to 14.003, and pulses the slide into position at 14.000 - perfect.
See section 5.1 for further details on slide adjust operation.
