6 POSITIONING CONTROL

6.22 Manual Pulse Generator Operation

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 Q173PXs are installed, connect the manual pulse generator to first (It counts from 0 slot of the CPU base) Q173PX.

(When the manual pulse generator is used, only first Q173PX is valid.)

[Control details]

(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] [Number of input pulses] [Manual pulse generator 1- pulse input magnification setting]

The travel value per pulse for manual pulse generator operation is shown below.
