10.2.2 Setting of Write Protect Switch
By setting the write protect function to “Protect” it is
possible to prevent the overwriting of parameters.
Write protection can be carried out using either the
hardware switch on the CPU board (i.e., Switch 2) or
software parameter settings. If either of these items is
set to “Protect”, the overwriting of parameters will be
prohibited.
NOTE
If the hardware switch is set to “Protect”, it will
not be possible to overwrite parameters; further-
more, this condition will be maintained until the
switch is set to “Enable”.
For more details regarding usage of the write protect
function and the software’s parameter switches, refer to
Chapter 6: Parameter Description.
