Hi guys. How can you test the zs of a motor run off an inverter drive?

    What happens with a dimmer switch though? I think you are all making it too hard. You wouldn't necessarily carry out Zs downstream of a dimmer, for fear of damaging it.


    If the inverter does not offer voltage collapse (crowbar) protection, it's just like a big dimmer switch.


    So, you take Zs before the inverter (dimmer switch or electronic switch) and R1+R2 downstream.
