INTRODUCTION

A-NDC 94 models are fitted into a metallic box of (110 x 108 x 34 mm). It is equipped with plug-in connectors, separated for power and logic sections. It is able to drive motors up to 2 Amps nominal current and it is the perfect choice for mid-power applications with small and mid-size stepper motors.

A-NDC is the name of the new mid-power bipolar microstep drive, specifically developed for applications sensitive to acoustic noise and vibration with STEP&DIRECTION interface (pulse train). The high precision microstep feature enables the system to reach 12.800 steps/revolution. It is characterized by a medium power range (up to 85 Vdc, 6 Amps), maximum compactness and great usage flexibility. All models are equipped with chopper systems featuring high performance mosfet power stage and protections for short circuit, overvoltage and temperature. Intelligent management of the current profile, in connection with adaptive microstepping innovative feature, achieves good results in terms of smoothness of movement.
