PARAMETERS
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.

0
Sampling starts when the value of the analog monitor exceeds
the value set at the trigger level (Pr.1037)

Sampling starts when the value of the analog monitor falls
below the value set at the trigger level (Pr.1037)

Set the level at which the analog trigger turns ON.
The trigger level is the value obtained by subtracting 1000
from the set value.
