The αSTEP ARD pulse input drivers substantially reduces heat generation from the stepper motor through the use of high-efficiency technology. In addition to implementing the closed loop control based on Oriental Motor's original αSTEP technology, the ARD drivers also achieves up to 40% less power consumption, low vibration, improved angle accuracy and is capable of driving large inertia loads. There is no hunting or gain tuning.
