Sigmatek SDD120-2 DIAS Drive
The Sigmatek SDD120-2 is a DIAS drive module for industrial automation. It is identified by the SDD120-2 model reference. The drive belongs to the Sigmatek DIAS system family. It controls electric motors for positioning, speed regulation and torque control. The SDD120-2 is used in packaging machines, printing presses, injection molding machines and robotics.
Drive Function
The SDD120-2 converts electrical power into controlled output for a motor. It adjusts voltage, current and frequency to achieve the required motion. The drive supports position, speed and torque control modes. It receives commands from the CPU module and feedback from encoders or resolvers. Closed loop control ensures accurate and repeatable motion.
Performance Characteristics
The drive is designed for high dynamic response and continuous operation. It provides smooth acceleration and deceleration. The module can handle fast cycle times and complex motion profiles. It supports synchronization with other axes through the DIAS system bus. Status LEDs indicate power, run, error and communication.
VARAN Communication
VARAN is a real time Ethernet protocol developed by Sigmatek. It provides fast and deterministic communication between the drive and the control system. VARAN allows short cycle times for synchronized motion. The interface supports daisy chain topology and reduces wiring complexity.
Applications
The SDD120-2 is used in many industrial machines. Typical applications include packaging lines, printing presses, injection molding machines, textile machinery, woodworking equipment and robotics. It is also used in handling systems, assembly stations and test benches.
Installation Notes
Installation should follow the drive manual. The module must be mounted in a compatible rack or cabinet with sufficient cooling. Power and motor cables should be sized correctly and shielded where required. Grounding is important for safety and noise reduction. After installation, parameters must be set for the motor and application.
Maintenance
Regular maintenance includes checking cooling, connections and dust build up. Fault records should be reviewed for repeated issues. Only qualified personnel should service the drive.
Conclusion
The Sigmatek SDD120-2 DIAS Drive is a reliable motion control solution. It provides precise motor control, real time communication and dependable performance. Correct installation and maintenance help ensure long service life.
