SIGMATEK MDD111-L DIAS Drive Axis Module
Overview
The SIGMATEK MDD111-L is a DIAS Drive Axis Module designed for precise motion control in industrial automation. It is identified by the MDD111-L model reference. The module controls a single servo axis and integrates into the DIAS distributed system. It receives command signals from the main controller and supplies the correct current and voltage to the motor. The MDD111-L supports position, speed, and torque control. It is used in packaging, printing, handling, and machine tool applications. The module is built for reliable performance in demanding environments.
Axis Control Function
The axis module 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 MDD111-L supports tuning parameters for different loads and dynamics. It may include filters and observers to improve stability. The module also provides protection functions such as overcurrent, overvoltage, and overheating. These features help protect the motor and the module. Proper configuration and tuning are important for optimal performance. The module communicates with the controller through the DIAS bus.
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 MDD111-L integrates into this architecture through the DIAS bus. This reduces wiring complexity and improves diagnostics. The module 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.
