Is suction/Discharge gauge stable ?

[A.Mortezania]

Hi guys,

Yesterdays I was talking with my friend about inverter compressors.
I hadn't experience about this system up to now. I have a question, Suppose that suction pressure is on 70 PSI and discharge pressure is on 230 PSI (R22) and compressor are working on 100% capacity.

When inverter control system decrease compressor speed (By decreasing frequency), Do compressor's suction and discharge gauge change ?

I can understand that when speed changes displacement of compressor changes too, But will it influence the pressure of suction and discharge gauge ?

Do any of friends have this experience to share with me ?

Thanks
