3-12
3.5.5 Pr. 1, 2 Upper-limit/lower-limit frequency
These parameters can be used to restrict motor speed.
These parameters are used to set upper and lower limits on output frequency.
Pr. Name Initial value Setting range Description
1 Upper-limit frequency 120Hz 0 to 120Hz Upper limit of the output frequency
2 Lower-limit frequency 0Hz 0 to 120Hz Lower limit of the output frequency
(1) Set upper-limit frequency
● Use Pr. 1 Upper-limit frequency to set the maximum
frequency. If the frequency of the frequency
command entered is higher than the setting, the
output frequency is clamped at the upper-limit
frequency.
(2) Set lower-limit frequency
● Use Pr. 2 Lower-limit frequency to set the minimum
frequency.
● If the set frequency is less than Pr. 2, the output
frequency is clamped at Pr. 2 (will not fall below Pr. 2 ).
