Hello Autogen_8291775,

The rectified AC voltage can be measured at the DC link terminals at the PM.

At the output a pulsed AC voltage is measured. It depends on the frequency.
Therfore a TRMS multimeter (consider the frequency range), has to be used.

The drive is in default settings (v/f) and line voltage is connected.
Use the IOP, press the Hand button.
Press the "I" button and raise the frequency with the hand wheel.
At the output terminals a voltage has to be measured, which corresponds to the frequency.
Press the "0" button. The drive ramps down the frequency and the output voltage.

Take care, you're operating with power!
