Fatek PLC
I am using fatek FBs 32MN PLC. i need to run the nema stepper motor synchronized with induction motor’s speed with some ratio. in my case the speed of stepper motor will change as the speed of induction motor changes its speed, may be many times in a second. Problem is that the speed of stepper will be constant as before until i have to disable and then enable again HSPSO function. is there any solution that i can dynamically change the speed of stepper without disable and enable HSPSO function ?
Hi,
You can try with zero pulse output. Because with zero pulse the system can run continue and may be you can change the speed without HSPSO function disable/enable.
Update the result.
Thank You.
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.
Hi, Not much use this function.
But did you try with PLSO instruction directly ?
I have tried PLSO but, its limited to 2000 pulses frequency and i need high speed pulses 400000 to 900000 pulses.
