The SD4B Drive Controller by SIEB & MEYER offers a compact design with a width of only 25 mm, despite an increased nominal current of 13 A in the high current variant. Housed in an IP20 enclosure, it provides a wide range of functionalities. In addition to the Safe Torque Off (STO) safety function, it comes with integrated interfaces for CANopen and Modbus TCP. For enhanced communication with higher-level controllers, an optional multiprotocol real-time Ethernet interface is available. The user can also access a TTL encoder input and output, five digital inputs/outputs, and an Ethernet interface for easy parameterization.
SD4B Drive Controller enables sensorless operation for high-speed motors
The SD4B drive controller offers versatile operation modes for both synchronous and asynchronous motors. With its support for sensorless operation, it allows synchronous motors to run at speeds up to 240,000 rpm and asynchronous motors up to 360,000 rpm. This is made possible by high-frequency clocking up to 32 kHz. In addition, the controller also supports sensor-based control using TTL encoders. Its robust speed control enables efficient operation even with high inertia ratios of up to 1:100 between the motor and the tool.
Integrated Load Indicator for Precise Monitoring of Motor Performance
The integrated load indicator in the SD4B is a standout feature, as it eliminates the need for acoustic vibration sensors by analyzing the torque-producing current of the motor. This precise evaluation allows for accurate detection of changes in the motor’s load, enabling insights into tool breakage or wear. Additionally, the load indicator can detect contact between the tool and workpiece, facilitating flexible adjustment of machining feeds.
