Selection of Siemens V20 Inverter
|
|
Siemens V20 converter selection problem has a motor, rated frequency 400 HZ, voltage is three-phase 220 volts. Now I want to use the 6SL3210-5BE17-5UV0 converter to drive. This frequency converter input is 400V, output is 400V, want to change P0304 to 220 volts, P0310 to 400 HZ, I do not know if this is possible, Siemens technical support has been busy, queuing.
The rated power of the motor? If the rated power of the motor is larger than 7.5kW, it can only use three-phase 380V power supply, you do not do very well. The harmonic of the motor will be larger. Either input plus autotransformer or output plus harmonic reactor. It's more stable.
The motor is a custom-made motor, rated frequency must be 400 HZ, voltage is 220 volts three-phase, considering the 220 Volts CURRENT is relatively large,* more of this 0.75 KW converter amplified to 1.1 KW.

Is it not good to use single-phase 220V power supply for such a small motor? So output three-phase 220V is no problem. 400Hz is not a problem, it can be controlled by V/F.
