UIM2040CM is a NEMA#8 (20x20mm) smart servo stepper motor integrated with encoder, driver and motion controller, and can be controlled through CAN messages and TTL input signals. NEMA#8 (20x20mm) , All-in-one CAN interface smart servo stepper motor with encoder, driver and motion controller, in aluminum case. Robust DSP core and fault tolerance, fail safe user interface, with free debug/control software and complete SDK, lib, dll and C++, C# example codes. 1 - 128 micro-stepping, 24-36 VDC supply voltage and 0.4-2 Amp adjustable current. Running with no vibration/noise and high torque, good substitution of AC/DC servo motor at low speed. Closed-loop motion, high positioning accuracy, fast response, and high speed to 4500 rpm. Supports speed control mode, position control mode, backlash compensation, stall detection, and many other control functions. 3 inputs, 1 output, and 3 trigger modes to suppress the electrical noise. 11 actions can be attached to each input level change. All inputs can generate notification when triggered.
