5.7 Maximum frequency
HJ: Maximum frequency
• 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.

This function determines the 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.

5.8 Upper limit and lower limit frequencies
WN: Upper limit frequency
NN
: Lower limit frequency
• 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.
