Reverse rotation prevention selection (Pr. 78)
In some applications (fans, pumps) it is necessary to ensure that the motor cannot be reversed.
This can be achieved with Pr. 78.
The above parameter can be set when Pr. 160 = 0.
Set this parameter when you want to limit the motor rotation to only one direction.
This parameter is valid for all of the reverse rotation and forward rotation keys of the operation
panel and parameter unit (FR-PU04/FR-PU07), the start signals (STF, STR signals) via external
terminals, and the forward and reverse rotation commands through communication.
