2-16 Parameter Descriptions
7000-TD002A-EN-P – September 2007
Inverter Control Flags 1 [InvControl Flag1]
Linear Number: 265
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.
Bit Enum Text Description
