Acorn Advanced Homing sequence to marker pulse

[jj80909]

I would like to utilize the index pulse from the DYN4 servo drives, but back off index mark (change the state of the input) after it has been found so that I can use one input for all three drives.

If the following moves the X axis in the positive direction at 3 IPM until Input 2 closes: M106 /X P2 F3 , what is the proper sytax to have it move via M105 to change the state of input 3?

Is the prefered method? If not, what is?

This is my homing file..
INPUT1 = x switch
INPUT2 = Y switch
INPUT3 = Z switch
INPUT6 = all three axis ZRI paralleled up

Code: Select all

M106 /X P-6 F5   ;Back X off ZRI+ so next axis can use it

I think I figured it out:

M92 /X L1 ; Move to +X limit switch and back off until it clears.
M105 /X P-2 F1 ; Move -X at 1 IPM until input 2 closes.
M106 /X P2 F0.5 ; Move +X at 0.5 IPM until input 2 opens.
M26 /X ; Set X home position.

I'll have to test it our later this evening.

slodat,

Thanks for the info...very helpful.
