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
The content depends on the digits on the operation panel.
0 or no display
The value(s) "0" to the left of the leftmost non-zero value is(are) not shown in the monitor display. For example, if no trace data is in internal RAM,
the USB memory is not accessed, no trigger is detected, and the trace operation is performed, "1" appears. (not "0001")
• When copying the traced data to a USB memory device, the operating status of the USB host can be checked with the

LED display status
• During trace operation, the Trace status (Y40) signal can be output.
To use the Y40 signal, set "40 (positive logic) or 140 (negative logic)" in one of Pr.190 to Pr.196 (Output terminal function
selection) to assign function to an output terminal.
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
