Hey, i have a prob. with to identical VFD setup with
Siemens Micromaster 440,
they uses for 2 roller that feeds a metal belt
they have encoder feedback.
setup the micromaster for vector control with sensor (parameter 1300)
when we give order to drive in 5hz
and we take a look in siemens STARTER
we can see that that setspeed is 5hz but actual speed is 4.85 on one VFD and 5.2 on the other one.
Shouldn't the encoder see that one is driving to slow and then speed up little and the other way for the other one, any ides to solve this?
Thanks,
