 Operation outline
• This function is used to sample the status data (analog monitor and digital monitor) of the inverter, trace the sampling data
when a trigger (trace start condition) occurs, and stores 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 a trigger occurs in the trigger standby status, tracing is started and the trace data is stored.

Preparing a USB memory device
Select a USB memory device with ample capacity to store the necessary amount of trace data. When the trace
function is used in the recorder mode, use a USB memory device with at least 1 GB of free space.

1 to 255 Select the digital data (I/O signal) for sampling on each channel.
1 to 8 Select the digital channel to be the trigger.
0 Tracing starts when the signal turns ON
1 Tracing 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.
