Digital inputs
▪ The frequency inverter is equipped with 6 digital inputs.
▪ Digital input DI-EN is permanently programmed and is used to enable the
hardware.
▪ The functions of digital inputs DI1 to DI5 can be parameterised as required.
The digital inputs are electrically isolated. The DICOM1 reference ground for the
digital inputs is thus also electrically isolated. If the internal 24V source is used, the
internal GND must also be connected to the electrically isolated DICOM1 ground of
the digital inputs. A wire jumper can be used between GND and DICOM1 for this
purpose.
