SMC11 – Compact Microstep Controller
The extremely compact SMC11 microstep controller is a very simple and economical solution for controlling stepper motors to a phase current of 1.4A. With two corresponding boreholes, the printed circuit board with dimensions of only 36 x 36mm is prepared to be directly mounted on the rear side of a motor of the ST4118 or ST4209 series. The B-version with 2 shaft ends is required for this as the boreholes only exist in this version. The B shaft must then be cut to length. If you have any questions, please contact our Technical Hotline.
Please note that not every Nanotec stepper motor or linear actuator is PIN compatible to the motor socket on the SMC11.

- 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.
