Mains Input

The Multiaxis Motor Control Board filters the mains input (Figure 3) and then splits to

the DC link and the 22-V power supply. Both power supplies incorporate PFC. The

Multiaxis Motor Control Board works with mains input voltages of 85 to 264 VAC, 50

or 60 Hz. The mains input includes an EMI filter.

DC Link and PFC

To provide unity power factor with very low-level harmonic distortion in line current,

an Emerson AIF04ZPFC-01L module produces the 400-V DC link voltage (Figure 4).

The PFC works over all typical line voltages used worldwide.
