SMCI33 - Stepper Motor Controller with Closed-Loop Controller
All users who are looking for a favorably priced and compact microstep motor controller as well as a flexible and easy-to-operate closed loop positioning control will now find these requirements combined in an extremely compact housing (90 x 60 x 22mm).
The adjustable microstep controller from 200 to 25,600 steps/revolution enables quiet, uniform operating behavior and reduces system resonances while increasing the resolution capacity and the interchangeability in 3-phase and 5-phase motors. A phase current of 3A phase and a voltage of 24–48V enables speeds of more than 3000rpm to be reached.
The associated programming software even enables users without programming knowledge to quickly and easily program complex travel profiles (parameters such as current values and step resolution as well as distance, speed, ramp, pauses and grinding, 16 records in total) and then transmit them via the RS485 or USB interfaces to the SMCI33 motor controller. The system can then be started either in automatic mode from the PC or in standalone mode with an external signal. Alternatively, all commands can of course be operated via the well-documented ASCII code, where even multiple axle applications are possible via the smallest PLC.
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.

- 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.
