I have used PID blocks in many PLC logic designers. But here when I apply the same principle, it does not work.
Could you please give some tips to make it work?.
Pulse count or frequency representing the motor speed is the input. I need to control speed output. What should be the P,I and D. My typical setpoints will be 50RPM,25RPM,75RPM 100RPM.
The maximum RPM of motor is 100RPM.
The interesting thing is the PID compute function does not produce any value when there is a change. Currently the P is 20000, I=20, D=0
please help
Thank you
