• This function determines the

maximum value in line with the

ratings of the motor and load.

• Maximum frequency cannot be

adjusted during op eration. 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.
