Hi, I'm working on Invertor compressor using EVAL-M1-CTF620N3 controller board with EVAL-M1-101T-F048 controller. I have read manuals for both controller board and controller as well as EVAL-M1-IM535. But now I'm stuck. I want to make RPM stable. I know that the motor speed variation can be controlled by tuning the Kp and Ki values so I changed parameters Ques 62 : Speed regulator Proportional gain and Ques 63 : Speed regulator Integral gain but nothing happened.
Another issue is that my motor vibrates when it starts but it become stable at around 2200 RPM (4700 to 5700 counts). I believe that this issue is related to unstable RPM waveform. The following picture is my current "RPM waveform".
So, that's why I want help. Please help me clear my confusion and please mention if I've missed something.
Thanks. I'll be waiting for your guidance.
As we can see that there is always a load connected to the motor. We would recommend following the steps given in the document AN2020-12 Driving high inertia loads with iMOTION™2.0
Please let us know if it works or any further help is required.
