// The Initialization Completed Flag is changed to TRUE.
InitFlag := TRUE;
The axis parameters are set. When setting the parameters is completed, InitFlag is changed to TRUE.
If StartPg is TRUE, the setting of the In-position Check Time is changed.
If changing the setting of the In-Position Check Time is completed,
the setting of the Positive Software Limit is changed.
