Knowledge Base

If communication is no longer possible with the motor controller or the motor after a failed firmware update, the firmware can be uploaded manually.

Firmware update  for downloading: Firmwareupdate.zip

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/drives 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 a time-consuming process), the following interference-suppression circuit can be provided at each input in use. Inputs that are not required can be connected directly to the controller ground.


The motor controllers and motors with integrated controllers 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 don't exceed the maximum switching current or the maximum voltage of the selected controller/drive. You can find this information in the respective manual.

SMCI35: A load/PLC cannot be connected with this controller.
