Integrated Functional Safety via Dual Safe Torque Off (STO)
The key advantage of the Unidrive M300 series over standard open-loop drives is its integrated dual-channel Safe Torque Off (STO) system. Certified to SIL3 (Safety Integrity Level 3) and PLe (Performance Level e), these onboard safety terminals allow machine builders to implement critical safety circuits without the need for bulky external safety contactors. This embedded design significantly reduces electrical enclosure space, reduces wiring complexity, and cuts hardware procurement costs.
High-Performance Motor Control (RFC-A Mode)
-
RFC-A Technology: Utilizes an advanced Rotor Flux Control algorithm that provides excellent closed-loop current stability within an open-loop system. This provides exceptional speed stability under varying load conditions, strong low-speed torque, and fast dynamic response without an encoder.
-
Onboard PLC Programming: Includes an integrated controller compliant with the IEC 61131-3 standard, allowing simple logic scripts to be executed directly inside the drive to streamline system architecture.
-
Conformal Coated Circuit Boards: Sensitive internal electronics are protected by standard conformal coating, shielding the drive from conductive particulate matter, moisture, and high thermal stress.
Scalable Automation Networking and Quick Commissioning
-
System Integration (SI) Slot: Features a built-in SI option slot that accepts modular communication expansion boards. The drive can interface seamlessly with external PLCs using PROFINET, EtherCAT, Ethernet/IP, Modbus TCP, CANopen, and PROFIBUS.
-
10-Parameter Fast Setup: A quick-start guide printed directly on the front panel highlights the 10 essential parameters needed to quickly configure and start the motor.
-
Rapid Diagnostic LED Interface: Fitted with a high-contrast LED keypad for real-time status updates, current parameters, and straightforward fault tracking.
-
Configuration Cloning: Fully compatible with the optional AI-Back-up or AI-Smart Adaptor to clone, store, and transfer setup profiles via standard SD cards.
