 Trigger setting (Pr.1025, Pr.1035 to Pr.1037, Pr.1046, Pr.1047)
• Set the trigger generating conditions and trigger target channels.
Pr.1025 setting
0 Trace starts when inverter enters an fault status (protective function activated)
1 Trace starts when analog monitor satisfies trigger conditions
2 Trace starts when digital monitor satisfies trigger conditions
3 Trace starts when either of analog or digital monitor satisfies trigger conditions (OR)
4 Trace starts when both of analog or digital monitor satisfies trigger conditions (AND)
• Set the trigger generation conditions for the analog monitor.
Pr.1036 setting
0 Sampling starts when the analog data targeted for the trigger exceeds the value specified
at the trigger level
1 Sampling starts when the analog data targeted for the trigger has fallen below the value
specified at the trigger level
*1 For Pr.1037, set the number obtained by adding 1,000 to the trigger level.
• Set the trigger generation conditions for the digital monitor.
Pr.1047 setting
0 Trace starts when the digital data targeted for the trigger turns ON
1 Trace starts when the digital data targeted for the trigger turns OFF
 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.
Pr.1020 setting
0 Sampling standby
1 Sampling start
2 Forced trigger (sampling stop)
3 Sampling stop
4 Data transmission
• The read value of Pr.1020 is always "0".
 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.
