5.10 System Function Instructions
5.10.5 Read Inverter Trace (ITRC-RD)
5-240
The parameters are described in the following table.
The status configuration is shown below.
( 3 ) Programming Example
In the following programming example, trace data is read from an Inverter.
Two records of trace data are read from the Inverter that is connected to station 1 of the SVB–01 on circuit 1. The data
is stored in the area that starts with MW00100.
