• 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.

• 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.
