Pr. 1, 2 Upper-Limit/Lower-Limit Frequency - Mitsubishi FREQROL-E700 Manual

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.
1 Upper-limit frequency
2 Lower-limit 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 ).
