SMCI12 - Stepper Motor Controllers
The motor controller SMCI12 for stepper motors is exceptional in the ease with which it can be set up and installed. It is a cost-effective power module for series use. The motor controller makes numerous options available that would otherwise be associated with considerably larger space requirements and higher costs. Because of the ballast switching integrated in the motor controller, an external capacitor is often not necessary.
- Software-based dspDrive® current controller for optimal operating behavior at all speeds.
- Interpolated microsteps in the clock-direction mode so that smooth running of the high-resolution one-64th microstep can even be used in full step. As a result, the SMCI12 motor controller is particularly well suited for CNC and other multi-axis applications.
- Java-based programming language for the creation of autonomous, distributed application programs without a higher-level motor controller.
Please note: When the laptop you connect to our motor controller is plugged in, a USB isolator must be used to prevent damage to the motor controller. The USB isolator is not required when using battery power.

- Applying 24-V control signals to a motor controller with pure 5-V inputs
The motor controllers SMCI12, SMCI35, SCMI36 and SCMP33 have 5-V inputs. If a 24-V control signal is to be applied, it is essential that a 39kohm (0.25W) resistance be connected in series to each input in use.
- Suppression circuit for overcoupling of 24-V control signals
Depending on the cable type, routing and length, an overcoupling onto the neighboring control line may occur with 24-V control signals. In motor controllers with wide range inputs (5–24V), this can cause a second input that is not activated to be recognized as high. To prevent this without having to change the wiring (which can be an involved process), the following suppression circuit can be provided at each input in use. Inputs that are not required can be connected directly to the motor controller ground.
- Switching of a load or PLC via the outputs of the motor controller/Plug & Drive motor
The motor controllers and Plug & Drive motors have open collector outputs. To switch a load or PLC, you require a relay according to this circuit diagram. The flyback diode is required. Please note the maximum switching current or the maximum voltage of the selected motor controller. You can find this information in the respective manual.
SMCI35: A load/PLC cannot be connected with this motor controller.
- The firmware update failed – no more communication
If communication is no longer possible with the motor controller or the motor after a failed firmware update, the firmware can be uploaded manually.
