• Adjustable load current protection.
• Adjustable decay modes.
• Excitation modes: 1/2, 1/8, 1/16 step.
• Large passive heat-sink.
• Dimensions: 50 x 75 x 35 mm
The EN, CW, and CLK inputs are opto-isolated.
If you are connecting them directly to a microcontroller then we suggest ground the EN-, CW-, and CLK- pins with your microcontroller as per the diagram above.
EN (Enable input): If connected as per above diagram, grounding EN+ input will enable the motor drive outputs. Providing a logic high will disable outputs to the motor.
CW (Direction input): If connected as per above diagram, grounding CW+ input will cause the motor to rotate anti-clockwise (counter-clockwise). Providing a logic high will cause the motor to rotate clockwise. The direction of rotation also depends upon the motor coil polarity.
CLK (Step input): Continually pulsing the CLK+ input will cause the motor to step in one direction. Depending on the excitation mode setting (via switches SW3 & 4) the motor will step once per 1 to 16 pulses of the CLK+ pin.
