SIGMATEK SDD120-2 DIAS Servo Drive
Overview
The SIGMATEK SDD120-2 is a digital servo drive from the DIAS Drive series. It is identified by the SDD120-2 model reference. The drive controls servo motors with high precision and fast response. It receives command signals from a motion controller and supplies the correct current and voltage to the motor. The SDD120-2 supports position, speed, and torque control modes. It is used in automation systems that require accurate motion, such as packaging machines, printing equipment, and machine tools. The drive is designed for reliable performance in demanding industrial environments.
Servo Control Function
The servo drive uses feedback from an encoder or resolver to compare actual motor position with the commanded position. It adjusts output current to reduce error. This closed loop control provides accurate positioning and smooth motion. The SDD120-2 supports tuning parameters for different loads and dynamics. It may include filters and observers to improve stability. The drive also provides protection functions such as overcurrent, overvoltage, and overheating. These features help protect the motor and the drive. Proper configuration and tuning are important for optimal performance. The drive communicates with the controller through a digital interface.
DIAS System Integration
The DIAS system uses a modular architecture that allows drives and I O modules to be distributed close to the machine. The SDD120-2 integrates into this architecture through the DIAS bus. This reduces wiring complexity and improves diagnostics. The drive receives power and communication through the system connection. It reports status and fault data to the main controller. The modular design allows flexible system expansion. Technicians should confirm compatibility with the specific DIAS configuration before installation. Proper addressing and parameter setup are important. Following approved procedures helps ensure reliable operation.
