the linear encoder in the following conditions.
Linear encoder resolution =
Number of pulses (AP)
Movement amount (AL

(Note): Set the same value in AP, AL, and AM as the value set in the servo
parameter "Linear encoder resolution - Numerator (PL02)" and
"Linear encoder resolution - Denominator (PL03)".
Refer to each servo amplifier instruction manual for details.
When "Linear encoder resolution - Numerator (PL02)" is set to 1 [
m] and
"Linear encoder resolution - Denominator (PL03)" is set to 20 [
m], the
values of AP, AL and AM are shown below.
