1、VOLTAGE AND MOTOR: Drive power supply voltage up to 80VAC or 110VDC, AC or DC universal. Suitable for driving all of these 4, 6, 8 wire 2 phase and 4 phase stepper motors 2、LOW NOISE AND HIGH EFFICIENCY: The stepper motor driver features self tuning and new 32 bit servo micro step DSP technology to operate with ultra low vibration noise 3、ACCURATE CONTROL: Stepper motor driver adopts average current mode control and two phase sinusoidal output current control technology. Automatic reduction of idle current, idle current automatically stop, accurate current control makes the motor heat less 4、TECHNICAL PARAMETERS: Stepper motor driver supports TTL compatibility and optical isolation inputs with pulse response frequencies up to 300KHz 5、RESOLUTION AND PROTECTION: The motor driver has 4 dip switches, a total of 16 subdivided decimal and binary, 16 optional resolutions, up to 51,200 steps per revolution. Support short circuit, overvoltage, and overcurrent protection
