Key Features & Benefits
-
High Performance & Precision: Offers exceptional dynamic response for demanding applications, ensuring fast acceleration, deceleration, and highly accurate positioning.
-
Integrated Safety Functions: Built-in safety features (often referred to as “Safe Torque Off” or similar) help protect both personnel and machinery by preventing unexpected start-ups.
-
Advanced Control Technology: Utilizes vector control for superior low-speed torque and overall motor performance, even under variable load conditions.
-
Multi-Feedback Support: Compatible with a wide range of feedback systems (e.g., resolvers, encoders, sin/cos encoders), providing flexibility for use with various servo motors.
-
Comprehensive Communication: Supports various fieldbus interfaces (e.g., CANopen, PROFIBUS-DP, DeviceNet) for seamless integration into modern industrial automation networks.
-
Regenerative Braking Capability: Can handle regenerative energy from the motor during braking, which can be dissipated through an external braking resistor (if required by the application).
-
Compact Design: The E82EV751 2C is designed to save valuable panel space in control cabinets.
