●
Set the trigger generation conditions for the analog monitor.
For Pr. 1037, set the number obtained by adding 1,000 to the trigger level.
●
Set the trigger generation conditions for the digital monitor.
Start of sampling and copying of data (Pr. 1020, Pr. 1024)
●
Set the trace operation. The trace operation is set by one of two ways, by setting Pr. 1020 "Trace
operation selection" and by setting in the trace mode on the operation panel.
●
When "1" is set in Pr. 1020, sampling is started.
●
When "2" is set in Pr. 1020, a trigger is regarded as having been generated (for instance, a forced
trigger), sampling is stopped and the trace is started.
●
When "3" is set in Pr. 1020, sampling is stopped.
●
When "4" is set in Pr. 1020, the trace data in internal RAM is transferred to a USB memory device.
(Trace data cannot be transferred during sampling.)
●
To automatically start sampling when the power supply is turned ON or at a recovery after an
inverter reset, set "1" to Pr. 1024 "Sampling auto start".
