Series DRWS – Drives for the Control of Electric Actuation

Driver for Stepper motors, one size/version
100, 400 and 750 W

The DRWS drivers, compact and optimized in one size, have been especially studied for all Camozzi stepper motors. They are capable of controlling stepper motors with 2 phases and micro stepping feed. They are able to calculate the normal resonance frequency of the motors and optimize their driving. Moreover, they can reduce natural friction to a minimum during very slow rollings of the stepper motor, giving a continuous and very fluid (smooth effect) movement at any speed thanks to the Microstepping technique, thus achieving a 1/128 STEP resolution. Another function that has been integrated into the driver reduces vibrations to a minimum during rolling inversion or during sudden changes in speed. At initial ignition/ switching on, the DRWS drivers are able to calculate the inductance, the electrical resistance of the motor connected and the inertia of the motor, and saves these parameters inside in order to better manage the driving of the motors.
