Yaskawa iQpump1000 AC Drive Quick Start - Manual (Page 29)

Single-Phase Motor
Variable speed drives are not designed to operate with single phase motors. Using capacitors to start the motor causes excessive
current to flow and can damage drive components. A split-phase start or a repulsion start can burn out the starter coils because
the internal centrifugal switch is not activated. The drive is for use with three-phase motors only.
n Notes on Power Transmission Machinery
Installing an AC drive in machinery that was previously connected directly to the power supply will allow the machine to
operate at variable speeds. Continuous operation outside of the rated speeds can wear on lubrication material in gear boxes
and other power transmission parts. Make sure that lubrication is sufficient within the entire speed range to avoid machine
damage. Note that operation above the rated speed can increase the noise generated by the machine.
