Reverse Rotation Prevention Selection (Pr. 78); Extended Parameter Display (Pr. 160) - Mitsubishi Electric FR-D720-0.4K Instruction Manual

4.17.3 Reverse rotation prevention selection (Pr. 78)

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

Reverse rotation prevention

selection
The above parameter can be set when Pr. 160 Extended function display selection = "0". (Refer to page 163)
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 enclosure surface operation panel and
of parameter unit (FR-PU04/FR-PU07), the start signals (STF, STR signals) via external terminals, and the forward and
reverse rotation commands through communication.

4.17.4 Extended parameter display (Pr. 160)

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

selection
The above 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"(initial value), 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 58, for the simple mode parameters.)
When Pr. 160 = "0", simple mode parameters and extended parameters can be displayed.
REMARKS
When RS-485 communication is used to read the parameters with Pr. 551 PU mode operation command source selection ≠ "2", 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.
