General Mach Discussion / machine safty issue
« on: April 02, 2008, 01:52:10 PM »
reading some of these posts about spontanious machine runs.There needs to be a discussion about a basic hardwire start stop circuit for machine power.I would suggest a start stop button controlled contacter with the soft estop controlling a relay in series with the stop circuit.If someone has a basic circuit diagram they could post go for it Al

General Mach Discussion / signal split question
« on: April 01, 2008, 08:32:31 PM »
This will probably take someone with hands on signal experience but here goes.Weve established I have a complmentary or differential  quadrature signal.I.E. +-a,+-b, index. Can this signal be split using only +A,+B ,index and disregard the rest.Im wondering If I can close to mach and galil . or is an useless effort.It may be usefull to others in any case. thanks Al

General Mach Discussion / six phase stepper reprogram?
« on: March 16, 2008, 05:20:03 PM »
Is it possible to use the signal  for a six wire stepper to drive a six switch inverter bridge? this would solve my salvage the simodrive problem.I am also thinking of the small pic boards for robotic hobbyists.But I couldnt program one. Any input thanks Al

General Mach Discussion / siemens 6sc610 drive
« on: February 21, 2008, 10:41:35 AM »
Hello Iam new to this but I have a project.It is a acroloc vmc with the above controller.What I would like to do control the inverter section directly and and get rid of some old and propriatory electronics.I know the inverters take a pwm signal.My problem is the interface is a 16 pin two row connecter and I dont have a clue which pin is what.the siemens website has zip.does anyone have any info on this . or is there a way to identify pin function thankyou AL
