Core Functional Capabilities
- Power Rating: Drives heavy continuous, constant-torque machinery up to 250 kW (335 HP).
- Overload Limits: Delivers a robust 150% overload protection capacity sustained for 60 seconds.
- Control Algorithms: Employs open-loop V/F control paired with automated torque boost and slip compensation algorithms.
- Harmonic Shielding: Standardized with a built-in DC reactor to suppress network line harmonics and protect internal components.
- External Braking: Requires an optional external dynamic braking unit (such as the MDBU series) for high-inertia deceleration. [1, 2, 3, 4, 5]
