1. Core Philosophy and Series Capabilities
The FC-302 series bridges the gap between standard variable torque drives and high-end motion controllers. Its design integrates:
Adaptive Control Modes: Including VVC+™ (sensorless vector control) for high torque at low speeds without feedback, open-loop scalar (V/f), and support for closed-loop vector control with optional encoder feedback.
Robust Overload Capacity: Handles 150% overload for 3 seconds and 110% for 60 seconds, ensuring reliability under transient industrial loads.
Modular Architecture: Supports plug-and-play options for I/O expansion, communication protocols, safety features, and application-specific controllers (e.g., multi-pump, synchronizing).
Thermal Resilience: Advanced cooling designs (forced convection, cooling plate, or back-channel cooling) enable operation from -25°C to +50°C without derating.
