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.

Upper limit and lower limit frequencies

• 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.
