    Information

    Our SDB-40-100 is an electronic inverter to power sine-commutated brushless DC motors (BLDCs). It is rated for DC-link voltages between 20 V and 100 V and continuous phase currents up to 40 A (sine peak). The main purpose of our SDB-40-100 is to satisfy highest requirements regarding the dynamics of electrical drive systems. This allows extremely high sampling rates of up 100 kHz for all control loops, i.e., torque/current (CST), speed (CSV), and position control (CSP). All filters and feedforward terms are available at the full-scale sampling rate of 100 kHz and can be freely parameterized by you. All such features and the control parameters can be adjusted through our dedicated graphical PC interface that is included when you purchase our SDB-40-100. On the fieldbus level, real-time communication between a central control unit (e.g., a PLC or an IPC) and our SDB-40-100 is feasible through EtherCAT (CoE) or CANopen. For extremely high-speed applications, the EtherCAT interface provides an update rate of up to 30 kHz. By the combination of this extremely high sampling rate and the Distributed-Clock feature, we set new standards for highly dynamical multi-axis synchronization. Our SDB-40-100 is compatible with all common position-transducer interfaces including BiSS, SinCos, TTL incremental, Hall, Endat 2.2, and Hiperface. Our SDB-40-100 renders oscilloscope analyses obsolete during the startup process of drive systems. It provides a digital data-logging functionality (freely adjustable sampling rate up to 100 kHz) that makes all relevant control parameters digitally accessible. With its top-notch dynamics, our SDB-40-100 is the perfect universal servo inverter for driving, for instance, the very-fast-response RoboDrive motors to master even the most demanding drive challenges with technology supplied by only one single source that is named RoboDrive.
