Operation outline
● This function samples the status (analog monitor and digital monitor) of the inverter, traces the
sampling data when a trigger (trace start condition) is generated, and saves the resulting trace
data.
● When the trace function is set enabled, samplings are collected and the inverter goes into the
pre-trigger status.
● In the pre-trigger status, samples are collected, and the trigger standby status is entered when
sufficient samples for the number of pre-trigger samples have been collected.
● When the trigger is generated in the trigger standby status, the trace is started and the trace data
is saved.

If the data is short for the pre-trigger sampling,
the inverter goes into the pre-trigger state.
Pre-trigger sampling number
90%
Once the enough data is collected for trigger sampling,
the inverter goes into the trigger-ready state.
Pre-trigger sampling number
At trigger generation, samples equivalent to the 100 %
pre-trigger sampling number are collected and saved.
