About the change of parameter setting
When you change parameters of converter in current use which analog output or alarm has been set, if you
change items which affect to the output or alarm, the output may change suddenly after display of
"**COMPLETE**" and may generate alarm. If, especially, the output signal is being used for control, perform the
signal lock on the system side prior to changing parameters.
Caution on change of parameter setting
When you change parameter settings, parameters will be saved in non-volatile memory on return to measuring
display. Saved parameters have been maintained even power is off. However, when you change the parameter
and turn off the power before returning to the measuring display, parameters will not be saved. Thus you should
set the parameter again.
