Core Functional Capabilities
- Dual-Rating Performance: Automatically optimizes its internal electrical thresholds based on the attached machinery load type.
- Heavy Duty Rating (G): Drives continuous, constant-torque machinery up to 55 kW (75 HP) with a 150% overload capacity for 60 seconds.
- Normal Duty Rating (P): Powers variable-torque loads (such as large industrial ventilation fans or centrifugal pumps) up to 75 kW (100 HP) with a 110% overload protection threshold for 60 seconds.
- Control Algorithms: Features general-purpose open-loop V/F control alongside automatic torque boost, automatic slip compensation, and 4 independent programmable S-ramps.
- Electrical Safety: Equipped with standard built-in DC reactor networks to suppress line harmonics and buffer internal electronics against system line surges. [1, 2, 3, 4, 5]
