Accessories

This compact and high-performance stepper motor controller offers high functionality in a very small space. With the proven NanoPro software, it is possible to select between different modes and setting parameters, including the innovative, almost noise and resonance-free direct control of the stepper motors via the microcontroller in the dspDrive® procedure, in both open and closed loop operation.

The motor controller with a continuous output of 4A (briefly up to 6A/phase) only needs a supply voltage of 12 – 48V, and can thus replace much larger and also considerably more expensive devices in many applications.
The SMCI35 motor controller cannot be networked, but merely parameterized with a special adapter via the USB interface. Numerous predefined operating modes (speed, positioning, flag position, clock-direction, analog, etc.) are available that cover common applications. Also, the function of the digital inputs and outputs as well as that of the analog inputs can be freely configured. In conjunction with the integrated NanoJ programming language based on the Java standard, complete autonomous application programs can be implemented on the 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.

Programming Manual V2.7 from Firmware 25.01.2013 for NanoJ Easy V1.04
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.
