DC motor controller TM StepDrive

two-phase stepperdigitalprogrammable

Stepper motor driver with integrated power stage for SIMATIC ET 200®SP in coordination with Siemens Controlling and driving stepper motors within a modular PLC system: The TM StepDrive technology guarantees a high-precision current adjustment and enables fine positioning up to 1/256 step (approx. 51,200 positions per revolution (0.0070°/step) with a 200 stepper motor). Technical Details • Stepper motor controller with integrated power stage for SIMATIC ET 200®SP • The TM StepDrive 1x24..48V/5A 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 100 mA adjustable increments • Power supply from 24 to 48 VDC up to 1/256 microstep • Physical resolution: approx. 51,200 positions per revolution (0.0070°/step). An encoder with a counter should be considered for micro positioning. • Maximum step frequency: 250,000 steps/sec three digital inputs for limit and reference switches • Diagnostic LEDs (collective error, power supply, deactivation, digital input, motoris running) • two operating modes: positioning and technology object mode • two connection types: power stage and indexer • Online controller parameterising and diagnostic • Programming via STEP®7, TIA Portal® (from version V15) or via GSD(ML) file • Operating temperature: 0 to +60 °C • Short-circuit-proof, overload-protected • Approval: CE Important: the configuration files are not down-compatible. SIMATIC®, ET 200®SP, STEP®7 and TIA Portal® are trade marks of the Siemens AG.
