CiA 402 Folder Missing

About the cia402.0.pos-scale, I wrote 100 000 to just start with some value. My encoders are 23bit, therefore 8 388 608 pulses per motor revolution. On my current plasma machine I have a 1:10 planetary gearbox that I plan to use when I upgrade the machine motors to servo motors and LinuxCNC. The rack gear pitch diameter is 50 mm, therefore the circumference is 157.07963267949 mm. This the linear distance that the axis will travel for 1 revolution of the rack gear or 10 revolutions of the motor.

Therefore the cia402.0.pos-scale = ((encoder res * gear ratio)/distance per rev). I am not sure what value I should use for distance per rev - is it the linear distance per the rack gear revolution or the linear distance per motor revolution(that is linear distance per rack gear revolution / gear ratio)?
