History Monitor Function

This function monitors start history and current value history stored in the buffer memory of the Simple Motion module on the
operation monitor of an engineering tool.
Start history
The start history logs of operations such as positioning operation, JOG operation, and manual pulse generator operation can
be monitored. The latest 64 logs are stored all the time. This function allows users to check the operation sequence (whether
the operations have been started in a predetermined sequence) at system start-up.
For the start history check method, refer to the "Simple Motion Module Setting Function Help" of an engineering tool.
Set the clock of CPU module.
