Core Functional Capabilities
- Power Rating: Specifically optimized to drive continuous, heavy constant-torque machinery loads up to 355 kW (475 HP).
- Overload Limits: Delivers a robust 150% overload protection capacity sustained reliably for up to 60 seconds.
- Control Platform: Employs open-loop V/F control paired with automated torque boost, automated motor slip compensation, and 4 independent programmable S-ramps.
- Harmonic Shielding: Standardized with a built-in DC reactor to suppress network line harmonics and safeguard internal electronics from mains power fluctuations.
- External Braking Requirement: Due to massive current thresholds, this drive requires an external dynamic braking unit (such as two MDBUN series units paired in parallel) if your process relies on the rapid deceleration of heavy mechanical loads. [1, 2, 3, 4, 5, 6, 7, 8]
