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
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"
b031
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.
