4.2 DC Injection Multi-function Digital Input Command
• The DC Injection command will be active under the following conditions: the inverter is ready (i.e. not
in program mode or in a fault state), no run command is present, and the output frequency is less
than the Minimum Frequency (n016).
• The DC Injection Current Level is set by the standard parameter n089 (as a percentage of inverter
rated current).
• The DC Injection at Start and DC Injection at Stop parameters n090 and n091 have priority over the
external DC Injection command.
• Full range DC injection (n005 = 2) has priority over the external DC Injection command.
• The External Baseblock command has priority over the external DC Injection command.
• The RUN LED on the digital operator will be lit solid when the DC injection command is closed.
