GOOD MORNING, I have a YASKAWA V1000 drive, with this reference CIMR-VU4A0007FAA, its input is 380v to 440v, but my voltage is 220v, how can I connect it?

Good day. "Except that the drive brings the option of changing the input voltage, it would not be convenient to try to connect it to 220, an elevator transformer of adequate power will be more expensive than a new regulator" you could check first what options it gives you for the voltage input Regards

Hi ... you can't ... it would be a low input voltage fault ... in regards to supplying a three-phase inverter with single-phase current if you can always provide that the voltage is the one indicated by the inverter and is not delivering its maximum power since in a single-phase rectification the signal differs a little from the three-phase ..
