1-phase power input inverter is 3-phase outputs , therefore 1-phase motor is not able to drive.
Safety precautions
▼The inverter cannot be used in any device that would present danger to the
human body or from which malfunction or error in operation would present a
direct threat to human life (nuclear power control device, aviation and space
flight control device, traffic device, life support or operation system, safety
device, etc.). If the inverter is to be used for any special purpose, first get in
touch with the people in charge of sales.
▼This product was manufactured under the strictest quality controls but if it is to
be used in critical equipment, for example, equipment in which errors in
malfunctioning signal output system would cause a major accident, safety
devices must be installed on the equipment.
▼Do not use the inverter for loads other than those of properly applied
three-phase induction motors in general industrial use. (Use in other than
properly applied three-phase induction motors may cause an accident.)
