Creating a program to enable/disable the manual pulse generator
operation
A program must be created to execute a manual pulse generator operation. Consider the "required control data setting", "start
conditions" and "start time chart" when creating the program.
The following shows an example when a manual pulse generator operation is started for axis 1.
Required control data setting
The control data shown below must be set to execute a manual pulse generator operation. The setting is carried out with the
program.
n: Axis No. - 1
Refer to the following for the setting details.
Page 504 Control Data
Start conditions
The following conditions must be fulfilled when starting. The required conditions must also be assembled in the program, and
the program must be configured so the operation will not start if the conditions are not fulfilled.
*1 The interlock must be provided so that the buffer memory is accessed after Synchronization flag [X1] turns on. When no interlock is
provided, an unexpected value may be read or written.
