4PARAMETERS4.22.3 Reverse rotation prevention selection (Pr. 78)⋅⋅Misoperation prevention and parametersetting restrictionThis function can prevent reverse rotation fault resulting from the incorrect input of the start signal.ParameterNumber78Reverse rotation preventionselectionName Initial Value Setting Range Description0Both forward and reverse rotations0allowed1 Reverse rotation disabled2 Forward rotation disallowedSet 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 (FR-DU07),parameter unit (FR-PU04/FR-PU07), start signals (STF, STR signals) via external terminals, and the forward andreverse rotation commands through communication.4.22.4 Display of applied parameters and user group function (Pr. 160, Pr. 172 to Pr. 174)Parameter which can be read from the operation panel and parameter unit can be restricted.ParameterNumberName Initial Value Setting Range Description160 User group read selection 0172User group registered display/batch clear09999173 *1 User group registration 9999 0 to 999, 9999174 *1 User group clear 9999 0 to 999, 9999*1 The values read from Pr. 173 and Pr. 174 are always "9999".01Only the simple mode parameters canbe displayed.The simple mode and extendedparameters can be displayedOnly parameters registered in the usergroup can be displayed.(0 to 16)Displays the number of cases registeredas a user group.

(Refer to the parameter list, pages 55 to 67, for the simple mode parameters.)⋅ In the initial setting (Pr. 160 = "0") status, simple mode parameters and extended parameters can be displayed.REMARKS⋅ When a plug-in option is fitted to the inverter, the option parameters can also be read.⋅ When reading the parameters using the communication option, all parameters can be read regardless of the Pr. 160 setting.⋅ When reading the parameters using the RS-485terminals, all parameters can be read reagrdless of thePr. 551 Pr. 550 Pr. 160 Valid/InvalidPr. 160 setting by setting Pr.550 NET mode operation1 (RS-485) ⎯ Validcommand source selection and Pr. 551 PU mode operation0 (OP) Validcommand source selection.1 (RS-485) Invalid (all readable)2 (PU)(initial value)With OP: valid9999(auto-detect)(initial value)* OP indicates a communication optionWithout OP: invalid(all readable)Pr. 15 Jog frequency, Pr. 16 Jog acceleration/deceleration time Pr. 991 PU contrast adjustment are displayed as simple modeparameters when the parameter unit (FR-PU04/FR-PU07) is mounted.281
