, set according to the parameter setting
of ―Frequency Division Pulses of PG (X4)‖.
Typical value: pulse equivalent 0.001, screw pitch
10mm without a reduction box, Pn201=2500; screw
pitch 5mm, Pn201=1250.

Calculation
Pn202 = pulse No. of each encoder circle × 4 ×
mechanical deceleration ratio.
Pn203 = (screw pitch/ pulse equivalent).
Typical value: pitch 5mm, encoder 17-bit,
deceleration ratio 1:1, pulse equivalent 0.001mm,
Pn202＝16384; Pn203＝625.
Pitch 5mm, encoder 17-bit, deceleration ratio 1:1,
pulse equivalent 0.0005mm, Pn202＝8192; Pn203＝
625.
