DC motor controller 1-STEP-DRIVE

stepperdigitalintegrated

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 • 5 APEAK Phase current with 20 mA adjustable increments • Power supply from 24 to 48 VDC • up to 1/512 microstep • Physical resolution: approx. 102,400 positions per revolution (0.0035°/step). An encoder with a counter should be considered for micro positioning. • Maximum step frequency: 510,000 steps/sec • Chopper frequency selectable: 18, 20, 22 or 25 kHz 7 2 digital inputs for limit and reference switches • Diagnostic LEDs (over current, over temperature, driving instruction or Motor is running, etc.) • Controller modes: relative and absolute positioning, revolution mode, move to a reference point,... • Online controller parameterising and diagnostic • Programming via STEP®7, TIA Portal® (V12 to V14) • Operating temperature: 0 to +60 °C • Short-circuit-proof, overload-protected • Approval: CE • Included in delivery: CD-ROM incl. configuration file (HSP), application example and manual (pdf)
