The SC750 Series are single-axis, programmable digital brushless servocontrollers that provide closed-loop position, velocity, and torque control for brushless servomotors.
The family includes five functionally equivalent models—SC752 through SC756—that differ mainly in output capability and physical size, with peak power ratings from 2.2 kW up to 36 kW. These drives use resolver-based feedback for commutation and digital servo feedback, and they can also generate an encoder-emulation output with selectable quadrature resolutions up to 16,384 pulses per revolution for external devices. The platform supports ServoBASIC Plus programming and the Motion Dialogue development environment, along with features such as signature commutation for smooth low-speed torque, autotuning based on motor/drive selection, and a fully enclosed standalone design with internal power supply and shunt regulation. Power is supplied directly from the AC line for a high-voltage DC bus (with an optional 120 V input variant), and the drive incorporates multiple protection and diagnostic features including overtemperature, short-circuit, undervoltage/line protection, a front-panel status display, and a summary fault output.
