Refer to circular corner transitional option.
7.2.2. System parameters
In the SETUP submenu, press [F2] key to enter system parameters setting window, as shown in Fig. 7.3.
Numerator/denominator ratio of electronic gear----
The numerator/denominator ratio of electronic gear is pulse equivalency in
micron.
Numerator < 65535, denominator < 65535.
Example: if the pulse equivalency of system is 0.008mm, its numerator/denominator ratio of electronic gear = 8/1.
Electronic Gear Ratio
= Pitch of Screw Rod × 1000(360 × Subdivision Number / Stepping Angle × Drive Ratio)
The computation method(adjustment method) of electronic gear is as follows:
