Invert
There is a logical invert function associated with the PowerFlex 750-Series drive’s
digital outputs. For the PowerFlex 753, it is configured by P226 [Dig Out Invert],
and for the PowerFlex 750-Series Option Module, it is configured by P6 [Dig
Out Invert]. This invert function changes the output status bit from a zero, false
state, to a one, true state, and vice versa.
This logical invert function requires power to be applied to the drive’s control
module for the drive’s logic to be active. This can be obtained from powering up
the drive’s control module by either applying power to the drive’s input section or
from an external 24VDC being wired into the Auxiliary Power Supply Option
Module.
