• This function determines the
maximum value in line with the
ratings of the motor and load.
• Maximum frequency cannot be
adjusted during operation. To
adjust, first stop the inverter.
"If HJ is increased, adjust the upper limit frequency WN as necessary.

Note: The output frequency is limit ed to a frequency 10.5 times as high as the b ase frequency (XN). Even if the
maximum frequency (HJ) or the upper limit frequency (WN) is set above this f requency, this limitation is
imposed on the output frequency.!Moreover, the output frequency increases up to 1.2 times the ma ximum
frequency (HJ) when the control that exceeds the maximum frequency (HJ) is necessary.!

• Function
1) Programs the range of frequencies output by the inverter (maximum outpu t values).
2) This frequency is used as the reference for acceleration/deceleration ti me.
• Function
Programs the lower limit frequency that determines the lower limit of the ou tput frequency and the upper limit
frequency that determines the upper limit of that frequency.
