Advanced Motor Control via RFC-A Technology
The drive incorporates the proprietary Rotor Flux Control (RFC-A) algorithm. This advanced control method uses closed-loop current control in an open-loop configuration, offering maximum stability of induction motors across all power bands. It stabilizes running speeds under highly variable loads, delivers excellent low-speed torque, and optimizes transient motor performance without requiring an external feedback device.
Modular Connectivity and Fieldbus Flexibility
The M200-03400073A includes an on-board System Integration (SI) slot that accepts external communication modules. This permits straightforward integration with existing plant PLCs and supervisory systems. Supported industry-standard communication networks include:
-
PROFINET
-
EtherCAT
-
Ethernet/IP
-
Modbus TCP
-
CANopen
-
PROFIBUS
Quick Setup and Commissioning Features
