Chapter 4 Explanation of Functions
4-51
4.2.44 Software lock (SFT) function
The software lock function allows you to specify whether to disable
rewriting of the data set for functional items. Use this function to protect
the data against accidental rewriting.
You can select the functional items to be locked and the method of locking as described below.
When using an intelligent input terminal for this function, assign function "15" (SFT) to one of the terminal [1] to [8]
functions (C001 to C008).
Function code Data SFT terminal Description
b031
00 ON/OFF
Disabling rewriting of items other than "b031" (when SFT is on) or
enabling rewriting (when SFT is off)
01 ON/OFF
Disabling the rewriting of items other than "b031", "F001", "A020",
"A220", "A320", "A021" to "A035", and "A038" (when SFT is on) or
enabling rewriting (when SFT is off)
02 ― Disabling the rewriting of items other than "b031"
03 ―
Disabling the rewriting of items other than "b031", "F001", "A020",
"A220", "A320", "A021" to "A035", and "A038"
10 ― Disabling rewriting except in the mode allowing changes during operation
4.2.45 Forcible-operation from digital operator (OPE) function
The forcible-operation function allows you to forcibly enable the inverter
operation from the digital operator when the digital operator is not
selected as the device to input frequency and operation commands. An
intelligent input terminal is used to turn this function on and off.
When the intelligent input terminal to which the forcible-operation function is assigned is off, frequency and operation
commands are input from the devices selected by functions "A001" and "A002". When the terminal is on, the device
to input frequency and operation commands is forcibly switched to the digital operator.
If the input device is switched while the inverter is operating, the current operation command is canceled and the
inverter stops the output. When restarting the inverter operation, turn off the operation command that was to be
entered from each input device for safety's sake, and then enter a new operation command.
Item Function code Data Description
Terminal function C001 to C008 31 OPE: Forcible operation
4.2.46 Forcible-operation from terminal (F-TM) function
The forcible-operation function allows you to forcibly enable the inverter
operation via control circuit terminals when the control circuit terminal
block is not selected as the device to input frequency and operation
commands. An intelligent input terminal is used to turn this function on
and off.
When the intelligent input terminal to which the forcible-terminal operation function is assigned is off, frequency and
operation commands are input from the devices selected by functions "A001" and "A002". When the terminal is on,
the device to input frequency and operation commands is forcibly switched to the control circuit terminal block.
If the input device is switched while the inverter is operating, the current operation command is canceled and the
inverter stops the output. When restarting the inverter operation, turn off the operation command that was to be
entered from each input device for safety's sake, and then enter a new operation command.
