
* 1: These are parameters set by setup menu. Default setting value is "jp". Refer to section 11.5.
Note1) Do not set a value 10 times larger than  (base frequency 1) and  (base frequency 2) for .
If a large number is set, the output frequency can only be output at 10 times of minimum value  and
 and a-05 alarm is displayed.
Note2) Output frequency lower than parameter f240 (Starting frequency) is not output. Parameter f240
setting is needed.
Note3) When the stall prevention function operates, the inverter may drive beyond the limit frequency ul or ll.
