11.4 Manual pulse generator operation
11.4.1 Outline of manual pulse generator operation
Important
Create the sequence program so that "
Cd.21
Manual pulse generator enable
flag" is always set to "0" (disabled) when a manual pulse generator operation is not
carried out.
Mistakenly touching the manual pulse generator when the manual pulse
generator enable flag is set to "1" (enable) can cause accidents or incorrect
positioning.
Manual pulse generator operation
In manual pulse generator operations, pulses are input to the QD75 from the
manual pulse generator. This causes the same No. of input pulses to be output
from the QD75 to the servo amplifier, and the workpiece is moved in the
designated direction.
The following shows an example of manual pulse generator operation.
1)
When the "
Cd.21
Manual pulse generator enable flag" is set to "1", the BUSY signal
turns ON and the manual pulse generator operation is enabled.
2)
The workpiece is moved corresponding to the No. of pulses input from the manual pulse
generator.
3)
The workpiece movement stops when no more pulses are input from the manual pulse
generator.
4)
When the "
Cd.21
Manual pulse generator enable flag" is set to "0", the BUSY signal
turns OFF and the manual pulse generator operation is disabled.
