Description of stepper motor SM4247 with integrated controller SMD‑1.6mini ver.2
Stepper motor with integrated driver SMD‑1.6mini ver.2 is designed and manufactured taken into account the rich experience of our company's specialists and the latest circuitry. Thanks to the design and new engineering solutions, SMD‑1.6mini ver.2 drivers provide excellent dynamics of stepper motors, fast acceleration and sufficient torque at high speeds.
When using a stepper motor with an integrated driver, the consumer receives the following benefits:
- Finished assembled product – motor with control unit. There is no need to prepare commutation. Motor and driver are connected and tuned for optimal performance;
- Save space - it is not necessary to provide an additional installation space for the driver;
- The absence of extra wires that could reduce the reliability of the design, especially in the moving mechanisms
Connection of stepper motor SM4247 with integrated controller SMD‑1.6mini ver.2
When controlling a stepper drive with pulse logic signals, the driver processes the input signals STEP (pulse), DIRECTION (level) and ENABLE (level). Control inputs can be connected with common cathode and common anode.

Serial port connection is required to set parameters or control a stepper drive via UART. For most computers without a built-in COM port, an UART/USB interface converter must be used.
The connection of the USB-UART interface converter with the SMD‑1.6mini ver.2 driver is shown below. The RX and TX pins of the driver are connected to the TXD and RXD pins of the converter, respectively.

Software for stepper motor SM4247 with integrated controller SMD‑1.6mini ver.2
The drive provides configuring motor control parameters via serial port. It is also possible to directly control the motor with commands from a PC or PLC. SMD mini control software is designated for quick parameterization of the drive, as well as for performing a given movement, setting speed and acceleration, starting and stopping the motor, turning on/off motor phases.
