5.2.2 Line Contactor Control for Line Modules with DRIVE-CLiQ Interface
Line Modules with DRIVE-CLiQ interface can control an external line contactor. The closing
and opening of the line contactor can be monitored by evaluating the feedback contact of the
line contactor. This control ensures that the line contactor always switches in a defined
manner and so prevents overloading or damaging the line contactor and/or the infeed.
The line contactor can be controlled using the r0863.1 bit of the INFEED drive object (for
840D sl and 16 kW to 120 kW Line Module).
Note
For further information about the line contactor, refer to the device manuals.
Note
If the line contactor should also be safely disconnected (safety), the control must be
integrated in an existing safety control. This is required so that the line contactor is switched
in accordance with the required safety categories. Also refer to the "Safety Integrated"
section.
5.2.3 Line Contactor Control Commissioning using an Example
Assumption:
● Line contactor control using a digital output of the Control Unit (DI/DO 14)
● Line contactor feedback using a digital input of the Control Unit (DI/DO 7)
● Line contactor switching time less than 100 ms
Note
Based on the macro preassignment, the parameterization of the pins 4 and 10 on the
X132 interface must be changed.
