PG DRIVES TECHNOLOGY AC TRACTION – DIAGNOSTICS
1 Error Detection
If the controller detects an error, it can be displayed in up to four different ways.
Firstly, the red LED on the controller itself will flash. The number of flashes in the sequence will reflect the error code.
The error code can also be read by the Programmer. It will be displayed as a number (preceded by ‘F’), on the right-hand side of
the Controller Type screen as shown below.
The Programmer’s Status menu also allows both the current and previous error codes to be viewed. See section, Status, for more
details.
Lastly, the Sigmagauge display can signal an error, using specific icons. Refer to the Sigmagauge chapter for further details.
