Мини степпер active инструкция

For customers interested in higher volumes at lower unit costs, we offer a bulk-packaged version without header pins and a bulk-packaged version with header pins installed. The carrier’s printed circuit board is designed to draw heat out of the IC, but to supply more than approximately 1 A per coil, a heat sink or other cooling method is required. However, in order to safely use voltages above the rated voltage of a stepper motor, the coil current must be actively limited to keep it from exceeding the motor’s rated current.

This product can get hot enough to burn you long before the chip overheats. Take care when handling this product and other components connected to it. The newer A4988 offers overcurrent protection and has an internal 100k pull-down on the MS1 microstep selection pin, but it is otherwise virtually identical to the A4983. The VREF pin voltage is accessible on a via that is circled on the bottom silkscreen of the circuit board. Категория: Спортивные товары Тип товаров: Мини-степпер Брэнд: Torneo.

For more information, please see the frequently asked questions. For instance, driving a motor in quarter-step mode will give the 200-step-per-revolution motor 800 microsteps per revolution by using four different current levels. Unipolar motors with five leads cannot be used with this driver.
