Update means, I just have to open hspso table and then close it.
Do you have any email ?

Hi IAS,
I appreciate your suggestion.
I have sorted the issue. I was making a mistake. Somewhere in middle of the code, i was using MOV function with double register thats why i was unable to move the value to SR+2 register. But now my code is working fine.
And again i really appreciate your suggestion

I have tried PLSO but, its limited to 2000 pulses frequency and i need high speed pulses 400000 to 900000 pulses.

Hi IAS,
I meant to say that if i use R1000 as a SR register then R1002 that will be “high alarm register” it refused to take the value and retain its value to zero. There is no SR+9 register is in manual.
Or may be i can’t understand you. Could you please brief me ?

Thanks for your quick reply,

I have already been using zero pulse output because i need to run my stepper motor endless but with dynamic frequency. i have sorted the issue actually, the MPARA function is making trouble . when i use the MPARA function with HSPSO function then i can not give it dynamic frequency. Do you have any solution for that ? i have already tried dynamic frequency register which is R4056 but, it only works HSPSO without MPARA function.
