Trigger setting (Pr.1025, Pr.1035 to Pr.1037, Pr.1046, Pr.1047)
• Set the trigger generating conditions and the trigger target channels.
Pr.1025
setting
0
Tracing starts when inverter enters a fault status (protective function activated)
1
Tracing starts when analog monitor satisfies trigger conditions
2
Tracing starts when digital monitor satisfies trigger conditions
3
Tracing starts when either of analog or digital monitor satisfies trigger conditions (OR)
4
Tracing starts when both of analog or digital monitor satisfies trigger conditions (AND)
• Set the trigger generation conditions for the analog monitor.
Pr.1036
setting
Sampling starts when the analog data targeted for the trigger exceeds the value specified
0
at the trigger level
Sampling starts when the analog data targeted for the trigger falls below the value specified
1
at the trigger level
*1
In 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
Tracing starts when the digital data targeted for the trigger turns ON
1
Tracing starts when the digital data targeted for the trigger turns OFF
Start of sampling (Pr.1020, Pr.1024)
• Set the trace operation. The trace operation is set in Pr.1020 Trace operation selection.
• 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.
• 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.

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.
Sampling retry
• If any error is found in the trace data, the sampling stops and then restarts (sampling retry).
• If another error is found within a minute from when an error is found, the sampling stops (sampling retry count excess).
• The sampling retry status can be checked by monitoring the trace status.
