Key Notes for Selection
- Current Matching: Ensure motor rated current ≤ 290 A (HD) or ≤ 290 A (LD) for reliable operation.
- Derating: Altitude >1000 m or temperature >40 °C requires output current derating (follow ABB DriveSize tool).
- Accessories: Frame E0 requires external brake chopper for dynamic braking; communication modules are field-installable.
