Reverse Rotation Prevention Selection (Pr.78); Extended Parameter Display (Pr.160) - Mitsubishi Electric FR-E700EX Instruction Manual

Misoperation prevention and parameter setting restriction

4.16.3 Reverse rotation prevention selection (Pr.78)

This function can prevent reverse rotation fault resulting from the incorrect input of the start signal.

prevention selection
The above parameters can be set when Pr.160 Extended function display selection = "0". (Refer to page 182)
 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)

Parameter which can be read from the operation panel and parameter unit can be restricted.

 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.
(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.
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.
