Start of sampling and copying of data (Pr.1020, Pr.1024)
• Set the trace operation. The trace operation is set by setting Pr.1020 Trace operation selection.
• When "1" is set in Pr.1020, sampling is started.
• When "2" is set in Pr.1020, a trigger is regarded as having been generated (for instance, a forced trigger), sampling is
stopped and the trace is started.
• When "3" is set in Pr.1020, sampling is stopped.
• When "4" is set in Pr.1020, the trace data in internal RAM is transferred to a USB memory device. (Trace data cannot be
transferred during sampling.)
• To automatically start sampling when the power supply is turned ON or at a recovery after an inverter reset, set "1" to
Pr.1024 Sampling auto start.

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 of 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.
