 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.

1 to 8 Select the digital channel to be the trigger.
0 Trace starts when the signal turns ON
1 Trace starts when the signal turns OFF
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.
