Available in thelist of constants:SdoAbortCodes.Table 6.25 DD_WriteParameter4_ISD51x6.5.4.24 DD_Trace_ISD51xThis function block is used to carry out a real-time tracewithin the axis using the settings given in the inputvariables. When the settings are sent and the trace started,the function block automatically polls the axis until thedata has been recorded and then uploads the dataautomatically. Information about the status of the tracingcan be monitored using the Status output (while Busy isTRUE).Inside the axis, the data is sampled over time, meaningthat there is an adjustable time difference between thesamples (use inputs SamplingRate and SubSampling). Forgeneral tracing capabilities, refer to chapter 2.7.2 Trace.The Abort input is used to abort the current functionality.The output CommandAborted is used to signal a successfulaborting procedure (see Illustration 6.48). The abort of thefunctionality can take some time.The behavior of output CommandAborted is similar to theDone output, only for a successful aborting procedure.If there is an error during aborting, the Error output is setto TRUE and the error reason is indicated at outputErrorInfo. The output CommandAborted stays as FALSE inthis case (see Illustration 6.49).For function blocks with Execute as Abort input, the Abortinput (and any other inputs of the function block) is onlyevaluated at a rising edge of Execute.ExecuteAbortBusyDoneCommandAbortedStartfunctionalityAbortfunctionalityError130BE948.10Illustration 6.48 Behavior of Successful Abort of FunctionalityProgramming Programming GuideMG36D102 Danfoss A/S © 01/2017 All rights reserved. 1916 6
