■ Adjustment range and display of parameters
JK : An attempt has been made to assign a value that is higher than the programmable range. Or, as a result of
changing other parameters, the programmed value of the parameter that is now selected exceeds the upper
limit.
NQ : An attempt has been made to assign a value that is lower than the programmable range. Or, as a result of
changing other parameters, the programmed value of the parameter that is now selected exceeds the lower
limit.
If the above alarm is flashing on and off, no setting can be done of values that are equal to or greater than JK or equal
to or lower than NQ.
