Single-Phase Motor
Variable speed drives are not designed to operate with single phase motors. Using capacitors to start the motor causes a high-
frequency current to flow to the capacitors and can damage the capacitors. 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.
Notes on Power Transmission Machinery
n
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 out 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.
