SMD-4.2DIN ver.3 - stepper motor driver

The stepper motor controller is engineered to handle motors with a current per phase rating of up to 4.2 A. This model offers  STEP/DIR positioning and analog speed control. The controller is known for its remarkable motor dynamics and high torque performance.

The SMD-4.2DIN ver.3 offers various options for controlling stepper motors:

• Pulse Position Control through external signals.
• Analog Speed Control Modes:
- Voltage signal in the range of 0 to 5 VDC.
- Voltage signal in the range of 0 to 10 VDC.
- Built-in potentiometer.
- External potentiometer.

Depending on the specific task, the controller can be used in one of the following control modes:

Pulse Position Control: Ideal for precise positioning tasks using standard control signals STEP and DIR. In this mode, the enable signal ENABLE can also be inverted.

Analog Speed Control Mode: Utilizing an external or built-in potentiometer, or analog voltage signals in the 0 to 5 V or 0 to 10 V range, this mode is suitable for tasks involving the precise maintenance and regulation of speed. The controller employs a built-in generator to set the pulses. This mode is used in scenarios involving simple motor movement (rotation) or when using an external source of "STEP" pulses is not feasible.
