> Choosing the power supply unit:
The AFE200 must be capable of delivering a current of ≥ 220 A
Choose the size with the appropriate characteristics from the section
trical data" on page
AFE200-61320.
> Choosing the drive:
Choose the size with the rated current required by the motor (≥ 236A) from the
catalogue (section ADV200-DC "2.7 Output Data"):
With a 650 Vdc drive:
ADV-71600-...-DC (In = 270A, OK).

Checking total DC-link capacity:
AFE200-61320 with ADV-71600-...-4-DC = 13600 + 16800 = 30400 μF ≤ 43000 μF
(OK). See table on page 48.
