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.

Sampling start
Sampling data
If the data is short for the pre-trigger sampling,
the inverter goes into the pre-trigger state.

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