How to calculate servo drive pulse/rev coefficient was created by aleksamc
Hi, all.
Before now I've worked with stepper motors. But now I have servodrives. How to calculate coefficient of pulse/mm ratting for this servo?
What formula I should use. My motor have 8mm per one turn. Servo drive (EP1C) also have parameters to set numerator and denumerator do pulse/rev coeffic. Should I use this also?

scale = pulses per 1 revolution of the motor x number of turns of motor to get one linear unit of axis movement.
1000 steps per rev motor with a 8mm pitch lead screw = 125 steps per mm
with metric threads it's probably easier if you use the reciprocal of the pitch (so threads per unit)
1000 x (1/8) = 125
If there is a belt or gear drive you must account for that too of course.
If you can set the steps per revolution of your drive then you must find out what that is first.
