Number of pulses/travel value at linear servo use
Motion CPU
Command AP
Control
value units
AL
Calculate the number of pulses (AP) and travel value (AL) for the linear encoder in the following conditions.
Linear encoder resolution =
Linear encoder resolution: 0.05 [m]
Number of pulses (AP) [pulse]
Travel value (AL) [μm]
Set the number of pulses in "Number of pulses per rotation", and the movement amount in "Travel value per rotation" in the
actual setting.
Set the same value as the value set in the fixed parameter to the servo parameter "PS02 (Linear encoder resolution setting
Numerator)" and "PS03 (Linear encoder resolution setting Denominator)".
Refer to the following for details.
