There is a button on the front of the VFD that will cycle through RPM, Freq, and a few other readings. If there is a >> button on your VFD, that will work. If there is a mode button on your VFD, that should works as well.
There is a >> disc button but it does not cycle through the display modes.
Is there a parameter setting to make this button work to cycle thru the display modes?
setting the starting rpm
the vfd will not start the motor
Any progress on this? I have the same issue.
What model is your VFD?
Mine is a YL620-G-5.5Kw
That model will not be able to show RPM. You will be able to show the frequency, which can be used to determine the RPM. RPM equals the Frequency x 60.
There is an Icon for RPM at the top of the display I cannot cycle through the different options to see the RPM
At the top of my control panel is has 6 different lights which indicate what your seeing. in order from left to right they are COM, ALM, DISP, RUN, Hz, RPM I have seen the ALM light up on initial set up but that was fixes with a parameter change. The run light shows up when i turn the spindle on and and it is running. I am however not able to get any of the other lights to show or to get the RPMs to display
If you do see an RPM light on the display, that panel sticker may be a sticker used for many types of VFDs and the RPM is not used. There is parameter: P00.24 which allows you to pick what to display. The choices a
0: Display current target frequency. This will display your knobs, potentiometer, setting, not the actual spindle frequency.
1: Display electric machinery run frequency. This will display the actual frequency that the VFD is currently sending to the spindle.
2: Display electric machinery run current: this will display the current the spindle is currently drawing.
3: Display input AC voltage. Self explanatory.
4: Display mother line voltage. This will display the actual voltage at the input.
5: Display output voltage. This will display the voltage at the UVW terminals for the spindle.
6: Display speed paragraph number SPx. I believe this displays which frequency is being selected (P07.00 to P07.07, or 1 to 8 respectively).
7: Display inverter temperature. This is the temp of the VFD, self explanatory.
8: Display input signal X1-X3/output signal. This simply shows the inputs/outputs associated with the external terminals.
9: Display user variable. This one I have not delved into, so it may be something to look into.
10: Display user count value. Same, this one could be useful.
11: Display temporary debugging variable. Haven't tried this one, so I can't inform of any useful information but it won't pertain to this subject anyway.
12: Display automatic multisegment run step and time. I haven't delved into this one either, but it won't show RPM.

How to display RPM instead of frequency on the VFD? I have the 2.2kv 110 volt spindle and inverter.
