 When the drive starts, it operates according to the V/F curve and accelerates from the minimum 
output frequency (Pr.01-07) to the setting frequency. It is not limited by the lower output frequency 
settings. 
 Use the frequency upper and lower limit settings to prevent operator misuse, overheating caused 
by the motor’s operating at a too low frequency, or mechanical wear due to a too high operation 
frequency. 
 If the frequency upper limit setting is 50 Hz and the frequency setting is 60 Hz, the maximum 
operation frequency is 50 Hz. 
 If the frequency lower limit setting is 10 Hz and the minimum operation frequency setting (Pr.01-
07) is 1.5 Hz, then the drive operates at 10 Hz when the Frequency command is higher than Pr.01-
07 but lower than 10 Hz. If the Frequency command is lower than Pr.01-07, the drive is in ready 
status without output.
