about ENABLE pin:
in industrial driver ,there are two signal (Pulse and Dir) but if we want use IC drive(sample :L297) for build driver, we have three signal(Pulse, Dir and Enable) .
In the industrial driver ,part of the embedded    Task: If the pulse is applied,then Enable pin is enabled.
If the enable pin is active for all times, power IC and motor Will be very hot.

i dont understand your issue.
you use servo motor for spindle,if yes then you can use speed monitor in Driver.

i test with digital driver. In this way ,when i connect S-ON pin to GND, motor lock( dont can rotate with hand ) and motor stationary.
now with analog drive ,when connect S-ON to GND motor stationary BUT i can rotate shaft with hand To both sides.
What difference there?

i think i have Ground issue.
yes , i also connect range 0 ~ +-10V and motor rotate .all thing is ok but i have noise in system.i think
in addition my driver dont have position mode.

i have a question about analog servo driver.
there are a pair wire for analog input(+-10V) ,when i connect this two wire (i mean 0V for analog input),i see motor rotate a little ,While must motor Remain motionless. i use yaskawa driver.
why?

One of the cool things that I like about this system that is not advertised on the MachMotion site, is the electronic gear box parameters.  The servos have 2500 lines on the encoders that generate 10,000 pulses per revolution that would normally make for a very slow system.  However, the electronic gear box setting allow you select the resolution on the axis you want

you have a 2500 line encoder that is 10,000 pulses per revolution
so if connectd direct with for example 5mm ball screw then you would need 10,000/5 =2000 steps per unit
at 3000rpm that would be 2000 x 3000 =6,000,000 pulse per min
divide by 60 and you get 100.000KHz pulserate required.
then i think you need SS for 100Khz.

now electronic gear ,i think we can use for when i dont want use SS.
for example , mach send 1000 pulse and gear box convert to 3000 pulse.
If I make mistakes,pls correct.

In the "Config" menu at top left, select "general config" then change the "IJ mode" from "ABS" to "INC".

Although I've applied these changes From the beginning, sometimes I encountered with this error.

For example: While cutting a circle
When press pause button while cutting and then start it again
why?

what IF we set up a brain to monitor the DRO/encoder like has allready been done. BUT instead of tripping a stop we write a macro to do a controlled stop, record current line of the program. RefHome the  axis then return to Currentline minus say 10 lines then" run from here" to restart??

i think for mach is best way.

and takes it into account for planning

i dont understand your mean.
