Hello Waiting to receive my CNC I am playing with my 2.2kw spindle and YL620 VFD It works, controled by the front panel knob for the moment, but I can not find how to display the spindle speed in rpm... Did not find in the user manual. The lighted LED is RUN and never RPM and it shows the target frequency (x10...!...) Do someone knows how to display spindle speed in RPM? Other question: what is the use of the 4 red switches on the attached picture and how to position them? The user manual is quite tricky even foggy...!... and the seller does not help ... Thank you
I've just tested it on mine and I've found the setting the jumpers like this: Pin1=ON - Pin2=OFF Vi1 = 0v-10v and setting the jumpers like this: Pin1=OFF - Pin2=OFF Vi1 = 0v-5v. I hope it will be useful for someone else trying to set it up.
To show the rpm. Hit the display button a few times. It wil cycle through the different options. Switch’s. Not sure.
