Core Functional Capabilities
- Power Rating: Specifically engineered to drive large continuous, constant-torque machinery loads up to 400 kW (535 HP).
- Overload Limits: Configured with a heavy-duty application profile allowing a 150% overload threshold sustained for 60 seconds.
- Control Platform: Employs open-loop V/F control paired with automated torque boost and automated motor slip compensation.
- Harmonic Shielding: Standardized with a built-in DC reactor to suppress power grid line harmonics and protect internal electronics.
- External Braking: Requires an external dynamic braking unit (such as multiple MDBUN modules configured in parallel) if your application involves high-inertia deceleration. [1, 2, 4, 5]
