V2.4e spindle RPM and on off

Hi,

First, are you positive the your VFD spindle input is 0-10V and cannot be configured to take 0-5V ? Some VFD can, depends on the model.

If it does required 10V PWM input, you may want to use a standalone 5V-10V stepup converter, that does not required any additional/external power, like those cheap things

Just tune that potentiometer such that you get 10V on the output when you put 5V in the input, then insert that module in series between your PWM output and the input on the VFD, and you should be good to go ?

p.s. here’s an old not-broken link with VFD discussion
