« on: September 25, 2008, 10:05:36 AM »
Helloo,

I have very big problem.I have 400 watt delta ac servo .I setup my system 1000 pulse for 1 mm and when I write G0 X+1 then G0 X0 .The servo dont get back start position.The servo company said that the mach3 not produce same pulse count.And I looked the servo online watch system when I said go +1 mm  produce 982 pulse then go the 0 (start point) it produce 943 pulse so 39 pulse miisng?

What is the problem? Ground problem or what? I am using shermil 1/2.I have direct parallel interface card for direction and step

Please give me advice

Mach will be sending the correct pulses but possibly your drives are not seeing them, try increasing the pulse width.

......................as ASD-B has NPN input for pulse n dir input n i guess its 24vdc..............make sure coz i've used it with the PLC n it does well.

Kindly use some high speed isolator card for 5vdc (lpt port) and 24vdc (drive side) power isolation .
