The AFE200 must be capable of delivering a current of ≥ 83A.
Choose the size with the appropriate characteristics from the section 10.6:
AFE200 - 4450.
> Choosing the drive:
Since the motors are used at below the rated power, the following inverters are
suitable:
Motor 1 : I
m
1 = 37A * 85% = 31.4A
Choose the size with the rated current required by the motor (≥ 31.4A) from the
catalogue ADV & AFE (section ADV200-DC “2.7 Output Data” on page 37).
With a 650 Vdc drive:
ADV-3185-...-DC (In = 34.2A, OK).
Motor 2 : I
m
2 = 37A * 90% = 33.3A
Choose the size with the rated current required by the motor (≥ 33.3A) from the
catalogue ADV & AFE (section ADV200-DC “2.7 Output Data” on page 37).
With a 650 Vdc drive:
ADV-3185-...-DC (In = 34.2A, OK).
