Key Features and Advantages:Pacific Scientific SCE904AN-002-01
Multi-Mode Control Flexibility: The SCE904AN-002-01 supports torque, speed, and position control modes, allowing users to switch between operational profiles based on application requirements. This flexibility is critical for applications like pick-and-place robots, where precise positioning is needed for assembly tasks, and packaging machines, where consistent speed control optimizes throughput.
Advanced Feedback Processing: With support for both incremental and absolute encoders, the controller ensures high-resolution position feedback (up to 2048 pulses per revolution), minimizing error and improving repeatability. This feature is essential in semiconductor manufacturing, where micron-level precision is non-negotiable.
Compact and Rugged Design: Measuring just 100 x 150 x 100 mm and weighing 1.5 kg, the controller fits into space-constrained cabinets without compromising performance. The IP20 enclosure protects against dust and accidental contact, while reinforced circuitry withstands voltage fluctuations and electromagnetic interference (EMI).
Seamless Communication Integration: The built-in Modbus RTU and CANopen interfaces enable easy integration with PLCs (e.g., Rockwell MicroLogix, Siemens S7 series) and human-machine interfaces (HMIs). This compatibility reduces integration complexity, allowing for centralized monitoring and control in large-scale automation systems.
Energy-Efficient Operation: The controller’s regenerative braking capability recovers energy during deceleration, feeding it back into the power supply and reducing overall energy consumption. This feature is particularly beneficial in high-cycling applications, such as conveyor systems or textile machinery, where energy savings directly impact operational costs.
