11.4 Manual pulse generator operation
11.4.1 Outline of manual pulse generator operation
Manual pulse generator operation
In manual pulse generator operations, pulses are input to the Simple Motion
module from the manual pulse generator. This causes the same number of input
command to be output from the Simple Motion module 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 "
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 number 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 "
Cd.21
Manual pulse generator enable flag
" is set to "0", the BUSY signal turns OFF
and the manual pulse generator operation is disabled.

(Note): Refer to Section 3.3 for input/output signal of LD77MS16.
[Precautions]
1: If the input from the manual pulse generator stops, the machine will decelerate to a stop.
2: The start complete signal does not turn ON in 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.
