Closed loop question

Hello friend 
i have a question about mesa card 
can mesa card closed loop axis with pwm like we have 3 axis and a spindle  mesa card output +/- 10 volt for all axis and spindle and get feed back from drives encoder or axis mounted encoders and make them full close loop for all axes . 
if can please give me model of mesa card that can do above opration 
By the way spindle is servo spindle has drive and built in encoder
thank you

Yes, a Mesa analog servo interface like a 7I77+7I92M or 7I97
can output +-10V for analog servos and accept encoder signals
allowing LinuxCNC to close the position control loop.

Sir what is the difference of mesa card close loop with commercial cnc close loop like fanuc haidenhien seimens is there any difference


Thank you

sir another question
in your opinion which is best for industrial servo driver like delta eston that work with both pulse/dir and analog +/-10
i want to purchase mesa card but i can not make a decision and choose between 7i97 or 7i76..
i want to know mesa close loop is best with step dir or analog pwm.
please help me on this i have three feed axis motor drive with (step/dir or pwm ) and one spindle with pwm .

thank you

sir i have drives and servo motors all work with both step/dir or pwm very well
my problem is with mesa card . if it does very well on step / dir closed loop i choose 7i76 or if mesa does very well in pwm i will choose 7i97
beside that my spindle only accept pwm +/-10v

thank you
