Thanks hood, now its more clear.. This smooth stepper has encoder inputs  ?? for carrying the encoder information to mach3 ?

so is that mean mach3 can drive a servo maximum 732RPM doesnt matter its nominal speed is 1000RPM or 6000RPM (if we are using a 8192 ppr encoder) ? in this case i want to ask you two more questions really important for me to solve the subject..,

1-) if our encoder is 2500ppr and nominal speed is 3000RPM, at 100Khz kernel it will turn 40rpm\s = 2400 rpm\m, how much Steps we need to send from motor tuning to get 2400RPM\m ? (2500 steps ?)

2-) i think This external pulsing devices are working well with mach3.. but i cant understand that how this boards increase the maximum speed of mach's ? (i mean, the source is 100Khz isnt there any delay ??)

Thank you very much for the reply.. There's one more thing, whats the relation between the PC's Processor ? i mean which processor speed i need minimum to run mach3 100Khz ?

i wonder that, how can you make that calculation ?

Hello i am new about this subject and trying to find a solution about some problems in my mind.. Assume that we have three 3000 rpm servo motor, has 8192 ppr encoders. With using 25.000Hz, 35.000Hz.... 100.000Hz, how many servo motors can run with using mach3 with a P4 2.0ghz processor ? Could you please help me about this calculation ??
