Product Overview
The FC-302P7K5T5E20H1BGXXXXSXXXXAXBXCXXXXDX is a heavy-duty VFD
engineered for extreme conditions. Its IP69K enclosure and
liquid-cooled heat sink enable operation in corrosive,
high-pressure, and explosive environments, such as offshore
drilling platforms and chemical processing plants. The model’s Adaptive Motor Control (AMC) algorithm provides 300% starting torque at 0.1 Hz, making it ideal
for high-inertia loads like centrifuges, extruders, and large
compressors.
Key Features
- Adaptive Motor Control (AMC):
- Adaptive tuning compensates for motor aging and load variations.
- Reduces harmonic distortion to <1% (THD) with integrated
Ultra-Low Harmonic (ULH) technology.
- AI-Driven Predictive Maintenance:
- Machine Learning Algorithms: Predict motor bearing failures, insulation degradation, and
cooling system leaks.
- Vibration Analysis: Monitors drive health in real-time via embedded sensors.
- Modular Safety Architecture (MSA):
- Safe Motion Functions: Safe Torque Off (STO), Safe Stop 1 (SS1), and Safe Speed Monitor
(SSM).
- Fieldbus Safety: PROFIsafe and CIP Safety over EtherCAT.
- IIoT Integration:
- OPC UA over TSN: Enables deterministic communication in real-time networks.
- 5G Ready: Facilitates wireless OTA updates and remote monitoring.
