Chapter 5 Data Used for Positioning Control
(Example)
• When an error does not occur
In the case of AP = 4194304 [PLS], AL = 2000000 [
10
-5
degree], and AM = 1,
the value is within the range as follows.

• When an error occurs
In the case of AP = 4194304 [PLS], AL = 10 [
10
-1

out of the range as follows.

Pr.2
Number of pulses per rotation (AP)
Set the number of pulses required for a complete rotation of the motor shaft.
If you are using the Mitsubishi servo amplifier MR-J4(W)-B/MR-JE-B/MR-J3(W)-B,
set the value given as the "resolution per servomotor rotation" in the
speed/position detector specifications.
Number of pulses per rotation (AP) = Resolution per servomotor rotation
Pr.3
Movement amount per rotation (AL),
Pr.4
Unit magnification (AM)
The amount how the workpiece moves with one motor rotation is determined by
the mechanical structure.
If the worm gear lead (
m/rev) is PB and the deceleration rate is 1/n, then
Movement amount per rotation (AL) = PB
1/n
However, the maximum value that can be set for this "movement amount per
rotation (AL)" parameter is 20000000.0
m (20m). Set the "movement amount per
rotation (AL)" as shown below so that the "movement amount per rotation (AL)"
does not exceed this maximum value.
Movement amount per rotation (AL)
= PB
1/n
= Movement amount per rotation (AL)
Unit magnification (AM)
Note) The unit magnification (AM) is a value of 1, 10, 100 or 1000. If the "PB
1/n" value exceeds 20000000.0
m (20m), adjust with the unit magnification
so that the "movement amount per rotation (AL) " does not exceed
20000000.0
m (20m).
1: Refer to Section 13.3.2 "Electronic gear function" information about electric
gear.
