High-Performance DC Brush Servo Drives

The SD45 is the latest addition to our high-performance servo drive family. Originally designed for commercial radar applications, including NEXRAD National Weather Service antennas and various military systems, the SD45 delivers exceptional reliability. It features a compact, rugged design, high current ratings, and failure-proof power and I/O connectors, ensuring durability in demanding environments. 

The SD45 is also engineered for industrial applications, offering cost-effective packaging and ratings to work in every application of DC brush servo drives.

The SD45 is a fully digital servo system, designed for easy installation and operation without the need for potentiometers. Whether you are an OEM, integrator, retrofitter, or end user supporting DC brush servo systems, the SD45 is the right solution.

Capabilities

DS45 is ideal single axis drive for DC brush motors with extended kit of functions and embedded system of graphical programming which allows to built applications for majority of technological processes where it is needed fast setup&run.

Features

Benefits

PLC with graphical programming language

Adaptation for logics of technological process without external PLC. Program can be created as block-diagrams, text, state-machines, algorithms and can use any events and digital/analog inputs for calculation of position/speed/torque command and digital/analog outputs as well as the values of all drive parameters.

Configuration software for PC

Fast tuning for different types of motors, regulators tune in auto- and manual mode, monitoring drives coordinates, parameters tune, 2-channel oscilloscope, system diagnostics

Log of faults and events

NV-memory storing of events history during drive work, with indication of time and sensors value (temperature, DC-bus voltage, load current, etc.)

Configurable protections

Following error, Over Voltage, Under voltage, Over Current, Short Circuit, I2T, OverTemperature. Mode of faults reset: auto (with automatic motor start), manual. 4 modes of faults indication and stop.

Acceleration/deceleration profile

Linear, S-curve, acceleration limitation (option)

Built-in generators

Fast tune of current and velocity regulators
