1–STEP–DRIVE–5A–48V Stepper motor module for the SIMATIC ET 200®S In Focus In coordination with SIEMENS ® The 1-STEP-DRIVE-5A-48V is a stepper motor controller with integrated power stage. It is specially developed for application in the decentralised SIMATIC ET 200®S peripheral system. SIMATIC ET 200 S with a fully integrated, egrated, powerful and high-precision positioning conng troller for 2 phase stepper motors. This 1-STEP-DRIVE module is configured via mouse click with the STEP®7 by using the provided configuration files and then parameterised. The module is ready for use in a very short time and supplements the Application examples for the 1-STEP-DRIVE module are assembly and transfer lines, building automation, x-y-tables, paper mills, printing and textile machines. Integrated Driver Application The 1-STEP-DRIVE-5A-48V module successfully completed the system compliance test performed by SIEMENS. These Phytron power stages are eminently suitable for not only setting the basic parameters via interface bus, but also the technological parameters found in the application. certain micro step positions cannot often be reached because of a lack of fine current settings and the motor may not reach the desired position. The 1-STEP-DRIVE technology guarantees a high-precision current The power stage can be optimised for the requirements of the drive system during commissioning. Furthermore it is possible to adjust the power stage during ´CPU RUN´, particularly for the next program sequence. For example, raise the stop current when the motor is holding a load and then reduce it as soon as the system comes to a standstill without the load to minimize the power requirement and motor heating. Using these functions combined with additional parameters bring out the best in your system. Fine positioning to 1/512 step Almost all commercially available stepper motor power stages can be operated in micro step mode. When driving the motor with encoder feedback, it is apparent that adjustment and enables fine positioning up to 1/512 step. The diagram above shows that a Phytron 200 step motor with encoder is able to be at each 1/512 micro step position with an absolute and non-cumulative error of about 0.0015°, typically much less than this. • Stepper motor controller with an integrated power stage for SIMATIC ET 200®S • For 2 phase stepper motors • 5 APEAK at 24 to 48 VDC • Up to 1/512 microsteps • Online controller parameterisation and diagnostics • STEP®7 programming Online parameterisation Edition 2015 March Extreme.
