Various functions: The stepper motor controller can adjust the angle, speed, direction and delay time of the motor. The micro-stepping resolution can reach 1/128, allowing you to control the motor more accurately. 9 operating states: The stepper motor controller has built-in 9 fixed operating modes, including suitable for ward rotation, reverse rotation, delay, cycle, etc., which can select the operating mode faster. In addition to the built-in parameter working mode, you can also control it through external buttons or other drives. [High-definition LCD display] The stepper motor controller is equipped with a high-definition LCD display, which can easily read parameters and set parameters more accurately. The module also has a power failure memory function to prevent your parameters from being lost. suitable for ward and Reverse Rotation: The stepper motor controller can change the direction of motor rotation by pressing a button, and you can also choose to use a range of working modes to choose two modes, automatic or manual. 13 menu setting functions: stepper motor controller includes cycle number, motor turn, delay time, number of pulses, suitable for ward speed, flip speed, etc. External buttons and rotary encoders make setting parameters very simple. color:Photo color Material:plastic Package Contents: 1 x controller 1 x plug wire Only the above package content, other products are not included.
