 | [[File:ioni_spu_scheme2.png|300px]]|| Two similar high power supplies are  used to supply both motor and logic voltages. In this system power of PSU1 and PSU2 will contribute to motor supply, i.e. if both supplies are rated 200W, then total power available to drives is ~400W. Diodes D1 is normally needed to protect power supplies from regenerative power and D2/D3 to protect power supplies in the case where one power supply would shut down (i.e. on overload). For recommended diodes, see the paragraph below.||
