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.
Additional Information:
There is a >> disc button but it does not cycle through the display modes.
Additional Information:
Is there a parameter setting to make this button work to cycle thru the display modes?
Additional Information:
setting the starting rpm
Additional Information:
the vfd will not start the motor
Additional Information:
Any progress on this? I have the same issue.
Additional Information:
What model is your VFD?
Additional Information:
Mine is a YL620-G-5.5Kw
Additional Information:
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.
Additional Information:
There is an Icon for RPM at the top of the display I cannot cycle through the different options to see the RPM
Additional Information:
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
Additional Information:
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
re:
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.
