 The upper / lower limit output frequency setting is used to limit the actual output frequency. If the
frequency setting is higher than the upper limit (Pr. 01-10), it will run by the upper limit frequency.
If output frequency is lower than lower limit (Pr. 01-11) and frequency setting is higher than min.
frequency (Pr. 01-07), it will run by lower limit frequency. The upper limit frequency should be set
> lower limit frequency. (Pr. 01-10 setting value must be > Pr. 01-11 setting value).
 Upper output frequency will limit the max. output frequency of drive. If frequency setting is higher
than Pr. 01-10, the output frequency will be limited by Pr. 01-10 setting.
 When the drive starts the function of slip compensation (Pr. 07-27) or PID feedback control, drive
output frequency may exceed frequency command but still be limited by this setting.
