SMCI35 – Stepper Motor Positioning Control with ClosedLoop
The very compact and powerful stepper motor output stage with integrated controller combines high functionality with the smallest space. When delivered, the controller is preset to clock direction mode. Current and step mode can be conveniently and suitably adapted via DIP switch. But also in the SMCI35, a choice can be made between very different modes and setting parameters with the proven NanoPro software. Thus, here again, customers can also benefit from the full range of know-how and functionality of Nanotec drive electronics accumulated over many years. In particular, the innovative, virtually noise and resonance free direct control of the end stages via microcontroller in the dspDrive® procedure can be applied in both open and closed-loop operation (current control via encoder) with minimum intrinsic development expense.
The final output stage with a continuous output of 4 A (briefly up to 6 A/phase) only needs a supply voltage of 12-48 V, and can thus replace much larger and also considerably more expensive devices in many applications.
The SMCI35 cannot be networked, but merely parameterized with a special adapter via the USB port. Numerous predefined operating modes (speed, positioning, flag position, clock direction, analog etc.) are available that cover conventional applications. Also the function of the 8 digital inputs and outputs as well as that of the two analog inputs can be freely configured. In conjunction with the integrated NanoJ programming language based on the Java standard, complete sequencing programs can be implemented on the board that can be run without a superordinate controller.

- 24V Suppression circuit
Depending on the wiring and cable length it is possible that a 24V control signal causes an overcoupling to another, 2nd control wire.
In case a controller with wide-range inputs (5 – 24V) is being used, this can result in malfunction of the controller. To avoid this, please integrate the following suppression circuit to all needed inputs. Inputs, which are not being used can be directly connected to Gnd.overcoupling, suppression circuit
- Connecting the motor controller or plug & drive motor to a load or SPS
Our controllers and plug & drive motors can be connected to a load or a SPS through their open collector outputs. A relay with the same circuit layout as shown in the picture is necessary. Further a catch diode is mandatory. Please, take the maximum switching current and the maximum operating voltage into account. You'll find this kind of information in the according manual.
