 Start of sampling and copying of data (Pr.1020, Pr.1024)
• Set the trace operation. The trace operation is set by one of two ways, by setting Pr.1020 Trace operation selection and
by setting in the trace mode on the operation panel.
• When "1" is set in Pr.1020, sampling starts.
• When "2" is set in Pr.1020, it is regarded that a trigger occurs (forced trigger), and the sampling stops and the tracing starts.
• When "3" is set in Pr.1020, sampling stops.
• When "4" is set in Pr.1020, the trace data in internal RAM is transferred to USB memory device. (Trace data cannot be
transferred during sampling.)
• To start sampling automatically when the power supply at power-ON or at a recovery after an inverter reset, set "1" in
Pr.1024 Sampling auto start.

• The read value of Pr.1020 is always "0".
• Trace operation can also be set in the trace mode on the operation panel.

 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.
