Parameter Descriptions 2-17
7000-TD002A-EN-P – September 2007
Inverter Control Flags 3 [InvControl Flag3]
Linear Number: 446
Access Level: Service
Read/Write: Read Only
This word indicates various status bits within the inverter control. The word can be used in trending to
assist in determining what the rectifier control is doing in a normal or abnormal situation. A 1 in a location
indicates that condition is active, and a 0 indicates the condition is inactive.

Inverter Analog Self Test Code 1 [InvAnlg SelfTst1]
Linear Number: 96
Access Level: Service
Read/Write: Read Only
This parameter specifies the power-up diagnostic results on the Analog Control Board. It refers to the
signals used by the inverter (Slave) processor. If the software detects a problem with the analog signals
into the board, or the board itself, an InvAnlg SelfTest fault will appear. This parameter will help indicate
which signals are causing the problem. The action should be to investigate all the connections and
feedback paths related to that signal before changing the ACB or the DPM. This is a self-test fault that
will only occur at initial power-up.
