Single--phase motors cannot be used
The inverter is not suited for the variable speed control of single--phase motors. Single--
phase motors are either capacitor start motors or split--phase start motors (the method
for determining rotation direction at startup is different). If a capacitor start motor is used,
the capacitor may be damaged by a sudden electric discharge caused by inverter out-
put. If a split--phase motor is used, the starting coil may burn because the centrifugal
switch does not operate.
