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

4.2.46 Forcible-operation from terminal (F-TM) function<br />
The forcible-operation function allows you to forcibly enable the<br />
inverter operation via control circuit terminals when the control circuit<br />
terminal block is not selected as the device to input frequency and<br />
operation commands. An intelligent input terminal is used to turn this<br />
function on and off.<br />

When the intelligent input terminal to which the forcible-terminal operation function is assigned is off,<br />
frequency and operation commands are input from the devices selected by functions "A001" and "A002".<br />
When the terminal is on, the device to input frequency and operation commands is forcibly switched to the<br />
control circuit terminal block.<br />
