Parameterization of the Signal Input Functions

Signal Input Function

Various signal input functions can be assigned to the digital signal inputs.

The functions of the inputs and outputs depend on the selected operating mode and the settings of the corresponding parameters.

WARNING
	UNINTENDED EQUIPMENT OPERATION Verify that the wiring is appropriate for the factory settings and any subsequent parameterizations. Only start the system if there are no persons or obstructions in the zone of operation. Carefully run tests for all operating states and potential error situations when commissioning, upgrading or otherwise modifying the operation of the drive. Failure to follow these instructions can result in death, serious injury, or equipment damage.
