●Compatible Models: Stepper motor controller fit for Nema17/23 Motor. The micro stepping resolution can reach 1/128, DC 5-30V ●High Definition LCD Screen: LCD screen can clearly display speed and cycle time. High definition display makes parameter setting and observation more clear and easy, and motor control more accurate. The controller parameters support the memory function screen that will not be lost, and the service life is longer ●9 Working Modes: Motor controller has set a variety of fixed operating modes, and can set distance/speed/delay/cycle times. You can select appropriate motion tracks to meet different scene applications. It can be run independently or used together with other systems ●13 Setting Functions:: The stepper motor controller including cycle number, motor turns, delay time, number of pulses, forward speed, flip speed, etc. The external buttons and knob encoder make it very easy to set the parameters ●Control Mode: The motor controller can control the direction and speed of rotation through buttons, external buttons, UART commands, other drivers or fixed working parameters.
