SA45 : CompletePower™ Motion Control
Technology: Bipolar Stepper Drive
Nominal Current: 5A and 10A
For Stepper Motors. Up to 500W.
This bipolar stepper drive features micro-stepping to 1/16 built into a fully enclosed rugged aluminum case. It can be DIN-rail mounted or panel mounted for fast integration. The mode of operation is set by simple DIP switches. Features include an internal oscillator that allows operation of the drive stand-alone or with an external analog speed reference (that scales this set frequency). Both 5A and 10A versions of this drive can be powered by the same range of voltage supplies. The pulse width modulated (PWM) power stage utilizes 95% efficient MOSFet technology and is protected against over-current and over-temperature. Connectivity is tool-free with RJ45-CAT5 plugs for the control inputs and push-type terminals for power. Supply an auxiliary 5V to power the optically isolated control circuit or use the internal 5V supply as preferred for the application.
