Stepper motor driver A-NDC 04

DC

► New series of bipolar microstep stepping motor drives, specifically developed for applications sensitive to acoustic noise and vibration. ► Significant evolution of the NDC series, preserving backward mechanical, electrical and applicative compatibility. ► Target: advanced applications requiring high precision, smoothness of movement and low acoustic noise. HIGHLIGHTS ► Full digital microstepping drive. ► Adaptive microstepping up to 12.800 step/rev (1/64). ► Intelligent management of the current profile that achieves good results in terms of smoothness of movement, low noise and vibration control. ► A highly sophisticated control system, preserving anyhow the traditional ease of use of R.T.A. drives. TECHNICAL SPECIFICATIONS ► Version: open frame drive in 101 x 94 x 25 mm, equipped with AMP connectors. ► Range of operating voltages: 24-85 VDC. ► Range of current: 0.6-2.0 Amp. Setting up to eight possible values by means of a dip-switch. ► Microstepping: 400, 800, 1.600, 3.200, 6.400 and 12.800 steps/revolution. Setting by means of dip-switches. ► Automatic current reduction at motor standstill. ► Management of the current profile setting by means of a dip-switch. ► Protections: -Protection against under-voltage and over-voltage. -Protection against a short-circuit at motor outputs. -Overtemperature protection with thermal sensor. ► Electronic damping facility for further acoustic noise and mechanic vibrations reduction. ► Optoinsulated inputs compatible to ensure best EM noise immunity. ► Warranty: 24 months.
