INDUSTRIAL APS TechnologyHigh performance stepper motor power stage Now as OEM module with sin/cos via SPI The phytron APS module is a high performance power stage for the operation of stepper motors up to 5 Apeak at 24 - 70 VDC with a shaft power up to 250 Watts. While almost any commercially available stepper motor power stage provides the setting of the so-called microstep operation, the generated current settings are too inaccurate to achieve the individual sub-steps and to approach the actual position. The APS module positions with an actual step resolution of 1/512 (102,400 positions per revolution with an encoder with a 200 step motor). Based on our parameteri-sable chopper technology and by the use of premium components with low resistance, the APS triggers with optimal timing. So the APS technology creates a current Specification shape close to a perfect sine wave minimum of heat loss in the controller. Only this highly accurate output signal enables the loss- and low resonance operation of the motor, the fast execution of each sub-step and the approach to each position. The compact APS is the core of the 1-STEP-DRIVE (for SIMATIC ET 200®S) SPS module and as a power stage module of our phyMOTION™ available. The APS can be parameterised (run current, stop current, boost current, current delay time etc.) and diagnosed online by a ServiceBus code and is also open for instructions from the CPU in runtime within a parameterisation cycle.
