Features:<br> Using 32-bit digital signal processing control technology, it is possible to set subdivision within 25600 and any multiple current values within the rate current.<br> The use of builted-in segmentation technology greatly improves the smoothness and noise under low segmentation.<br> Current setting can be freely selected between the rate values, and current automatically halves when at rest.<br> Pulse response frequency can reach up to 250KHZ, and it have protections functions such as overvoltage, undervoltage, and short circuits.<br> Driver integrates automatic parameters tuning function internally, which can automatically adjust the great operating parameters for different motors and maximizes the performances of the motors.<br> <br> Specifications:<br> Materials: Plastic<br> Size: about 14.2x9.7x5.3cm/5.59x3.82x2.09inch<br> Power supply voltage: 30AC-80AC<br> Working current: 2.1-8.4Amp<br> Logics input current: 10mA<br> Step time pulse corresponding frequency: 250KHZ<br> Pulse low level time: 2.5US<br> <br> Note:<br> Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order.
