Tips: What will the output torque be when the motor’s rotating speed changes?

Starting torque and maximum torque under the driving of VFD are smaller than those directly driven by power supply.
When the motor is powered by a power frequency supply, the starting and acceleration impact are huge. When the motor is powered by a VFD, the impact would be much weaker. Power frequency starting would produce a huge starting current. When a VFD is used, the output voltage and frequency of VFD are gradually added to the motor, so the starting current impact would be much smaller.

Existing reviews of 20 hp VFD, Single Phase to Three Phase VFD

Is there a way to program and delay in the VFD?

The VFD we purchased from you in April last year we are just now installing and attempting to run a 15HP rotary air compressor.

See attached specs on Air Compressor. The shore power or generator power supply is 220V single phase and we purchased the VFD to convert that [power to 208V 3 phase power for the air compressor.

The air compressor manufacturer is telling us they need 42 amps to run the compressor but 80 amps at start-up.

Is there a way to program and “delay” in the VFD to give it 5-10 seconds to start air compressor?

That is what the compressor people are telling me.

Also, this VFD only registers 50hz. It’s supposed to be 60hz correct?

Please advise.
