Misoperation prevention and parameter setting restriction
4.16.3 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-PU07), the start signals (STF, STR signals) via external terminals, and the forward and reverse rotation commands
through communication.
4.16.4 Extended parameter display (Pr.160)
(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-PU07). (Refer to the parameter list, page 52, 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.

0 Displays simple mode + extended parameters
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 communication is used to read the parameters, all parameters can be read, regardless of the Pr.160 setting.
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.
Pr.15 Jog speed setting, Pr.16 Jog acceleration/deceleration time, and Pr.991 PU contrast adjustment are displayed as simple mode
parameter when the parameter unit (FR-PU07) is fitted.
OP indicates a communication option.
