4.2.25 Reverse rotation prevention selection (Pr. 78)
Pr. 78
"reverse rotation prevention selection"
This function can prevent any reverse rotation fault resulting from the incorrect input of
the start signal.
!
Used for a machine which runs only in one direction, e.g. fan, pump.
(The setting of this parameter is valid for both the PU and CC-Link operations.)
