Operation Theorem
You can try this function:
_
7443_verify_speed(0,5000,&minAccT, &maxAccT,5000);
The value of minAccT will be 0.0267sec and maxAccT will be 873.587sec.
This minimum acceleration time can’t match our requirements, so we must
use over speed value to do that.
If we use over speed as 20000,
_
7443_verify_speed(0,5000,&minAccT, &maxAccT,20000);
The value of miniAccT will be 0.00666sec and maxAccT will be 218.387sec.
This minimum acceleration time still can’t match our requirements. If we use
over speed as 140000,
_
7443_verify_speed(0,5000,&minAccT, &maxAccT,140000);
The value of miniAccT will be 0.000948sec and maxAccT will be 31.08sec.
This minimum acceleration time can match our requirements. So, the
motion command will be like this.
_
7443_fix_speed_range(AxisNo,140000);
_7443_start_tr_move(AxisNo,5000,0,5000,0.001,0.001);
[Note1] The return value of _
7443_verify_speed() is a minimum velocity of
your motion command, it will not always equal to your start velocity setting.
In the above example, it will be 3pps more than your 0pps setting.
[Note2] Once you don’t need a fixed over speed setting, you can use
_
7443_unfix_speed_range() to disable it.
[Note3] Don’t try to use the over speed all the time, you must know when
you need it. Remember that more over speed setting will results in coarser
speed interval.
