The drives supplied withpower from the Smart Line Module have to use this signal as a ready signal. This ensuresthat a pulse enable can only be issued for the drives (motor or generator operation) when theinfeed is ready.If interconnection with a digital input on the CU is not possible, the signal must be evaluatedby a higher-level control system instead. It is not permissible that the control system sets thedrives to ready until the infeed "Ready" signal is present.Artisan Technology Group - Quality Instrumentation ...
