More variants, more possible uses

Small, compact, yet versatile and powerful: Drive controllers from the SD4B series from Sieb & Meyer score points as highly dynamic servo amplifiers for the operation of rotary and linear low-voltage servo motors. In addition, they can be used for optimized operation of high-speed low-voltage synchronous and asynchronous motors. In addition to the standard version, the Lüneburg high-speed specialists now also have a high-current version in their portfolio.

The SD4B series from Sieb & Meyer stands for a wide range of functions in a compact size, integrated in a space-saving IP20 housing. In addition to the standard version with 10 A @ 80 VDC, a high-current version with 13 A @ 48 VDC is now also available. Despite the increase in the rated current from 10 A to 13 A, the new version has retained its small construction volume and, above all, its small width of 25 mm.

Standard safety function and extensive interfaces

All models are equipped with the Safe Torque Off (STO) safety function and have interfaces for CANopen and Modbus TCP. A multi-protocol real-time Ethernet interface is optionally available for flexible communication with the higher-level control via EtherCAT (CoE), PROFINET IO or POWERLINK. To further simplify integration, the SD4B has a TTL encoder input and output as well as five digital inputs/outputs. Parameterization can be conveniently carried out via an Ethernet interface.
Angle-synchronous operation of several high-speed motors

In the high-speed range, the SD4B as a frequency converter allows sensor-based control based on TTL encoders in addition to sensorless operation of synchronous motors up to 240,000 rpm and asynchronous motors up to 360,000 rpm. In this way, for example, several high-speed motors can be operated in master/slave mode with angular synchronization, which is useful in the field of optical systems, among other things. The robust speed control also allows high mass inertia ratios between motor and tool of up to 1:100.

The devices in the SD4B series have NRTL/CSA certification, so that they can be integrated into systems for the US market without additional approvals. This makes the SD4B a future-proof solution for global applications.
