• 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.
ŬIf HJ is increased, adjust the upper limit frequency WN as necessary.

HJ Maximum frequency ~ Hz
Note: The output frequency is limited to a frequency 10.5 times as high as the base frequency (XN). Even if the
maximum frequency (HJ) or the upper limit frequency (WN) is set above this frequency, this limitation is
imposed on the output frequency.Moreover, the output frequency increases up to 1.2 times the maximum
frequency (HJ) when the control that exceeds the maximum frequency (HJ) is necessary.

maximum frequency (HJ) or the upper limit frequency (WN) is set above this frequency, this limitation is

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