Stepper motor module for the SIMATIC ET 200ŽS: 1-STEP-DRIVE 
Stepper motor driver with integrated power stage for SIMATIC ET 200ŽS
in coordination with SIEMENS 
Controlling and driving stepper motors within a modular PLC system: The 1-STEP-DRIVE technology guarantees a high-precision current adjustment and enables fine positioning up to 1/512 step with an absolute and non-cumulative error of about 0.0015° (Approx. 102,400 positions per revolution (0.0035°/step) with a 200 step motor).
