General Mach Discussion / Re: servo selection.......

« on: October 02, 2008, 02:04:45 AM »

Dont know what machine the OP has but just when he mentioned he was thinking of 4Nm Yaskawa I presumed it was probably more than just a Boss or similar, but maybe not.
Hood

Thanks for all your valuable feedback.

Dear Hood I got two old cnc machine made by (Kirloskar Indian manufecturer) Its 10 yrs old actually the system was fitted with their proparitry hardware n now they don't support for it any more. Its been laying at my frriend factory n he was abt to retrofit it with Siemens 810 cnc  ( he is in cranes and hoist manufecturing business.).
So i came up with my idea of turning this one machine into mach3 Pro CNC. And let it stand far above Siemens 810 in terms of features and performance.

This mach3 replacement has to be industrial grade so, i go with yashkawa coz its available in india.

The system integrator told me that this servo have simulated encoder o/p. That means for 2500 PPR i can have any PPR for mach3 from servo itself.

Once again thanks alot guys.

General Mach Discussion / Re: Delta ASD-B servo pulse problem (please help)

« on: October 01, 2008, 07:43:58 AM »

......................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 .

General Mach Discussion / servo selection.......

« on: October 01, 2008, 07:28:51 AM »

Hi all,
Can you guys help me out with servo selection  for milling machine.
I have an old milling machine and i want to fit it with mach 3 along with servos..............for better stability.
I have two cheap options for servo
                                                 A) Delta Electronics servo
                                                 B) Yashkawa  servo
I guess 4Nm will be good enough to start with but i am not sure what PPR to choose for encoder. 2500 PPR is the minimum available encoder resolution. And its a 3000 Rpm motor.
What is the max. encoder frequency that a mach3 can handle.
Would it be more accurate to use G100 with 600Mhz PIII  laptop  instead of high end desktop PC .

Thanks
