6 POSITIONING CONTROL

6.22 Manual Pulse Generator Operation

[Control details]
Positioning control based on the number of pulses inputted from the manual pulse
generator is executed.
Simultaneous operation for 1 to 3 axes is possible with one manual pulse generator,
the number of connectable modules are shown below.

POINT
• When two or more Q173DPXs are installed, connect the manual pulse generator
to first (It counts from 0 slot of the main base) Q173DPX.
(When the manual pulse generator is used, only first Q173DPX is valid.)
(1) Positioning of the axis set in the manual pulse generator axis setting register
based on the pulse input from the manual pulse generator.
Manual pulse generator operation is only valid while the manual pulse generator
enable flag turn ON.

(2) The travel value and output speed for positioning control based on the pulse input
from manual pulse generator are shown below.
(a) Travel value
The travel value based on the pulse input from a manual pulse generator is
calculated using the following formula.
[Travel value] = [Travel value per pulse]
