Chapter 5 Data Used for Positioning Control
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-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 (
μ
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
μ
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
μ
m (20m), adjust with the unit magnification
so that the "movement amount per rotation (AL) " does not exceed
20000000.0
μ
m (20m).

Pr.7 Bias speed at start
Set the bias speed (minimum speed) upon starting.
The specified "bias speed at start" will be valid during the following operations:
• Positioning operation-
• OPR operation
• JOG operation
Set the value that the bias speed should not exceed "
Pr.8
Speed limit value
".
