Knowledge Base

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 product manual.  SMCI35:  A load/PLC cannot be connected with this controller.
More details
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...
