 Selection of trace operation by input terminal (TRG signal, TRC signal)
• Trace operation can be selected by signal inputs.
• A forced trigger can be applied when the Trace trigger input (TRG) signal is ON.
• Sampling is started and stopped by the Trace sampling start/end (TRC) signal turning ON and OFF, respectively.
• To input the TRG signal, set "46" in any parameter from Pr.178 to Pr.189 (Input terminal function selection), and to
input the TRC signal, set "47" to assign the function to a terminal.
NOTE
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
 Monitoring the trace status
• The trace status can be monitored on the operation panel by setting "38" in Pr.52 Operation panel main monitor
selection, Pr.774 to Pr.776 (Operation panel monitor selection), or Pr.992 Operation panel setting dial push
monitor selection.
