Unit: Grade
Gear transmission ratio 70:4 => 4 load revolutions = 70 motor revolutions
Travel distance per motor revolution = 4/70 * 360° = 20.571 428 5 ...° (number
cannot be represented exactly)
Instead of this number, you have the option of entering it exactly as a numerator
and denominator:
Travel distance per motor revolution = 144/7
This will not result in any drift in continuous operation mode or in reset mode, even
with relatively long motion in one direction.

Unit: mm
Gear transmission ratio 7:4 => 4 load revolutions = 7 motor revolutions
Number of pinions: 12
Tooth separation: 10mm
Travel path per motor revolution = 4/7 * 12 * 10mm = 68.571 428 5 ... mm (this
number cannot be expressed exactly)
Instead of this number, you have the option of entering it exactly as a numerator
and denominator:
Travel distance per motor revolution = 480/7 mm
For "travel distance per motor revolution" that can be represented exactly, enter 1
as the denominator.
