alculate the number of pulses (AP) and movement amount (AL × AM)
for the linear encoder in the following conditions.
Linear encoder resolution =
Number of pulses (AP)
Movement amount (AL × AM)
Linear encoder resolution: 0.05 [
μ m] per PLS
1 [PLS]
=
Number of pulses (AP) [PLS]
=
20
0.05 [ μ m] Movement amount (AL × AM) [ μ m] 1.0
Set the number of pulses in "[Pr.2] Number of pulses per rotation (AP)",
the movement amount in "[Pr.3] Movement amount per rotation (AL), and
the unit magnification in "[Pr.4] Unit magnification (AM)" in the actual
setting.
: When MR-J4(W)-GF use, 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 [
μ m]
and "Linear encoder resolution - Denominator (PL03)" is set to 20 [ μ m],
the values of AP, AL and AM are shown below.
AP = 20 ……………. [Pr.2]
AL = 1.0 ………..….. [Pr.3]
AM = 1 …………...… [Pr.4]
