Phytron: Stepper Motor Module (SIMATIC ET 200®S: 1-STEP-DRIVE)
Stepper motor driver with integrated power stage for SIMATIC ET 200®S 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).
Technical Details
Stepper motor controller with integrated power stage for SIMATIC ET 200®S
The 1-STEP-DRIVE-5A-48V module successfully completed the system compliance test performed by SIEMENS.
Suitable for bipolar control of 2 phase stepper motors with 4-,(6-) or 8 lead wiring
