value is equal to the distance from negative OT location to the machine origin
(HOME). Figure below shows the relationship among the software OT limit, the
emergency stop, and the actual hardware limit.

11. Backlash Comp Format：□.□□□ (Default = 0.000)
Unit: mm
12. MPG-NUM Format：□□□□□□□ (Default = 100)
13. MPG-DEN Format：□□□□□□□ (Default = 100)
Ex1: For X-axis, MPG-DEN = 100 pulses, MPG-NUM = 100 m.
The resolution for X-axis = 100/100 = 1 m/pulse.
If MPG hand-wheel moves 1 notch (=100 pulses), the feed length in X-axis
= 100 × (100/100) = 100 m = 0.1 mm.
Ex2: For Y-axis, MPG-DEN = 200 pulses, MPG-NUM = 500 m.
The resolution for Y-axis = 500/200 = 2.5 m/pulse.
If MPG hand-wheel moves 1 notch (=100 pulses), the feed length in Y-axis
= 100 × (500/200) = 250 m = 0.25 mm.
※ Setting by engineer.
