DC motor controller CVD series

microsteppingtwo-phase steppersingle-axis

The CVD 2-phase stepper motors driver offers superior performance and value and is ideal for OEM or single axis machines. The CVD series stepper motor drivers offer: • Lowest Vibration and Noise with advanced Microstepping control • Significantly improves positional accuracy when microstepping • Highest torque with Bipolar configuration (4 lead wire) • Small, thin microstepping drive with space saving FETs • Selectable step angle and microstepping filter control • 2 mounting types and connector configuration • Alarms The CVD driver offers superior low vibration and noise characteristics by using the new, fully digital full-time microstepping control circuit. The new Smooth Drive microstepping feature with higher current control reduces the basic step angle to a maximum resolution of 2048. As a result, significantly reduced step vibration in the low speed range is achieved. For the mid speed ranges, the vibration has been suppressed enabling a more stable torque characteristic. In general, stopping accuracy tends to be lower during microstep operation than with full step operation. The CVD significantly improves positional accuracy during microstepping compared to that of other similarly manufactures microstepping drivers or commonly used ICs.
