value
Calculate the number of pulses (AP) and movement amount (AL) for the linear encoder in the following conditions.
Linear encoder resolution =
Linear encoder resolution: 0.05 [m]
Number of pulses (AP) [pulse]
Movement amount (AL) [μm]
Set the number of pulses in "[Pr.2] Number of pulses per rotation (AP)", and the movement amount in "[Pr.3] Movement
amount per rotation (AL)" in the actual setting.
*1 Set the same value as the value set in the fixed parameter to the servo parameter "Linear encoder resolution setting Numerator (PS02)"
and "Linear encoder resolution setting Denominator (PS03)". Refer to each servo amplifier instruction manual for details.
