FC 300 Programming Guide
Function:
controlled by bus.
Function:
Holds the preset level of Output X30/8.
In case of a bus timeout and a timeout
function is selected in 6-60 Terminal
X30/8 Output, the output will preset to
this level.
Function:
Select the function of Terminal X45/1 as an
analog current output.
When no signal on the analog output.
0hz = 0mA; 100hz = 20mA.

Value is taken from 16-37 Inv. Max. Current.
Inverter max. current (160% current) is equal
to 20mA.
Example: Inverter norm current (11kW) = 24 A.
