selection
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 140.)
⋅ 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 (FR-DU07),
parameter unit (FR-PU04), signals (STF, STR signals) via external terminals, and the forward and reverse
rotation commands through communication.

Parameter which can be read from the operation panel and parameter unit can be restricted.
Pr.159
In the initial setting, only the simple mode parameters are displayed.

(1) Display of simple mode parameters and extended parameters (Pr.160)
⋅ When Pr. 160 = "9999" (initial value), only the simple mode parameters can be displayed on the operation panel (FR-
DU07) and parameter unit (FR-PU04).(Refer to the parameter list, pages 38 to 50, for the simple mode parameters.)
⋅ Setting "0" to Pr. 160 enables the display of the simple mode parameters and extended parameters.
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 (simple mode, extended mode, parameters
for options) can be read regardless of the Pr. 160 setting.
⋅ When reading the parameters using the RS-485
terminal, all parameters can be read reagrdless of the Pr.
160 setting by setting Pr.550 NET mode operation command
source selection and Pr. 551 PU mode operation command
source selection.
⋅ Pr. 15 Jog frequency, Pr. 16 Jog acceleration/deceleration time, Pr. 145 PU display language selection, Pr. 991 PU contrast adjustment
are displayed as simple mode parameters when the parameter unit (FR-PU04) is mounted.
