Requirement
The line contactor control requires a 24 V power supply of the converter.
The 24 V power supply must be maintained, even when the line contactor is open.
Description of function
The converter controls its own line contactor using signal r0863.1 via a digital output.
The converter monitors the line contactor feedback signal in signal c0860.
When feedback signal is activated, parameter p0861 de󹪝nes the monitoring time of the line
contactor. If the feedback signal is not available for longer than the time set in p0861, then
the converter issues a fault.
