can i use this cct for g120c (1.5kw) if the motor is 0.18 kw ??????????

The attached circuit is using 'strapping', to produce a DC Voltage double that of the AC 230 Volt input.

The output is DC at some 640 Volts, connect this to two of the phase terminals of the inverter input, and also set Parameter P210 to its highest Voltage, 480Volts from memory.

This will be suitable for low power motors, if the load is too great the supply will collapse. It is possible that a pre charge circuit would be a beneficial modification, not something I put in however.

This works for Micromaster and Sinamics drives as demo units, I will leave you to interpret this circuit as safe to use in your application.

N.b. The caps are Electrolytic.
