Misoperation prevention and parameter setting restriction
4.18.3 Reverse rotation prevention selection (Pr. 78)
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.
4.18.4 Extended parameter display and user group function (Pr. 160, Pr. 172 to Pr. 174)
(1) Display of simple mode parameters and extended parameters (Pr. 160)
When Pr. 160 = "9999", only the simple mode parameters can be displayed on the operation panel and parameter unit (FR-
PU04/FR-PU07). (Refer to the parameter list , page 62 , for the simple mode parameters.)
In the initial setting (
Pr. 160
= "0") status, simple mode parameters and extended parameters can be displayed.
This function can prevent reverse rotation fault resulting from the incorrect input of the start signal.

Sets the parameter numbers to be cleared from
the user group
∗1
The above parameters can be set when Pr. 160 User group read selection = "0".
∗2
The values read from Pr. 173 and Pr. 174 are always "9999".
∗3
This parameter allows its setting to be changed during operation in any operation mode even if "0" (initial value) is set in
Pr. 77 Parameter write selection
.
REMARKS
When a plug-in option is fitted to the inverter, the option parameters can also be read.
When communication is used to read the parameters, all parameters can be read, regardless of the
Pr. 160 setting.
Pr. 15 Jog frequency , Pr. 16 Jog acceleration/deceleration time , and Pr. 991 PU contrast adjustment are displayed as simple mode
parameter when the parameter unit (FR-PU04/FR-PU07) is fitted.
When RS-485 communication is used to read the
parameters, all parameters can be read,
regardless of the
Pr. 550 NET mode operation
command source selection , Pr. 551 PU mode operation
command source selection , regardless of Pr. 160
setting.
