High-Stability Open-Loop Motor Control (RFC-A Mode)
-
RFC-A Technology: Incorporates an advanced Rotor Flux Control algorithm that provides excellent closed-loop current control within an open-loop design. This delivers superior dynamic speed response, transient load stability, and high starting torque without speed feedback hardware.
-
Onboard Logic Programming: Includes an integrated controller compliant with the IEC 61131-3 standard, allowing users to configure simple PLC automation logic sequences directly inside the drive.
-
Conformal Coated PCBs: Built with standard heavy-duty conformal coated printed circuit boards to defend internal electronic components against moisture, dust, and extreme temperatures.
Modular Network Connectivity and Rapid Setup
-
System Integration (SI) Slot: Features a built-in SI option slot to accept external communication modules. The drive can interface seamlessly with major plant PLCs via PROFINET, EtherCAT, Ethernet/IP, Modbus TCP, CANopen, and PROFIBUS.
-
Parameter Cloning Layout: Fully compatible with the optional AI-Back-up or AI-Smart Adaptor, allowing fast parameter backup and configuration cloning via standard SD cards.
