The variable frequency drive has the following ten protections on the motor:
Over-voltage protection: The variable frequency drive output has automatic voltage regulator function to control the external overtop power input to be not exceed the motor rated voltage.

If you want to connect a 3-phase motor to a single phase power supply, then you have several solutions:
1) use a VFD with a single phase input and convert to 3-phase output, this is generally available for low power VFD (few horsepower).
2) apply a specially wound transformer that also mimic a 3-phase system from a single phase power supply. Expect difficulties to source and high price.
3) calculate a capacitor that will be connected between the remaining phases, such to apply it a phase shift and to mimic a 3-phase system.
