Core Functional Capabilities
- Power Rating: Powers large variable-torque applications (such as industrial plant ventilation fans, high-volume centrifugal pumps, or bulk mixing systems) up to 280 kW (375 HP).
- Overload Protection: Tailored for normal-duty profiles with a 110% overload capacity sustained safely for 60 seconds.
- Control Algorithms: Uses general-purpose open-loop V/F control alongside automatic torque boost, automatic slip compensation, and four programmable independent S-ramps.
- Electrical Safety: Standardized with a built-in DC reactor to mitigate system power line harmonics and protect internal electronics against sudden voltage surges.
- External Braking: This large power platform requires an external dynamic braking unit (such as the MDBU series) if your process relies on the rapid deceleration of heavy mechanical loads. [1, 2, 3, 4, 5]
