* Notes, Important :
(1) Parameter 147 [FW Functions EN] is used to
activate and deactivate firmware functions. The
PowerFlex 700S drives ships with the position
regulator deactivated. To enable the position
regulator, set Parameter 147, bit 16 to 1 “On”.
(2) Parameter 1000 [UserFunct Enable] is used to
activate and deactivate the User Functions.
(3) These diagrams are for reference only and may
not accurately reflect all logical control signals;
actual functionality is implied by the
approximated diagrams. Accuracy of these
diagrams is not guaranteed.
