fatek HSPSO not working with dynamic speed Frequency change

[Kamran Ahmed]

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 ?
