CHAPTER 12: DESCRIPTION OF PARAMETER SETTINGS
63-4528—04 136
• The upper/lower output frequency setting is used to limit the actual output frequency. If the frequency setting is higher than
the upper limit, it will run with the upper limit frequency. If output frequency is lower than the output frequency lower limit and
frequency setting is higher than min. frequency, it will run with lower limit frequency. The upper limit frequency should be set to
be higher than the lower limit frequency.
• Pr.01-10 setting must be ³ Pr.01-11 setting. Pr.01-00 setting is regarded as 100.0%.
• This setting 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.
• Related parameters: Pr.01-00 Max. Operation Frequency and Pr.01-11 Output Frequency Lower Limit
• This setting will limit the min. output frequency of drive. When drive frequency command or feedback control frequency is
lower than this setting, drive output frequency will limit by the lower limit of frequency.
• When the drive starts, it will operate from min. output frequency (Pr.01-05) and accelerate to the setting frequency. It won’t
limit by this parameter setting.
• The setting of output frequency upper/lower limit is used to prevent the personal misoperation, the overheat due to too low
operation frequency and the damage due to too high speed.
• If the output frequency upper limit setting is 50Hz and frequency setting is 60Hz, max. output frequency will be 50Hz.
• If the output frequency lower limit setting is 10Hz and min. operation frequency setting (Pr.01-05) is 1.5Hz, it will operate by
10Hz when the frequency command is greater than Pr.01-05 and less than 10Hz. If the frequency command is less than
Pr.01-05, the drive will be in ready status and no output.
• If the frequency output upper limit is 60Hz and frequency setting is also 60Hz, it won’t exceed 60Hz even after slip
compensation. If the output frequency needs to exceed 60Hz, it can increase output frequency upper limit or max. operation
frequency.
