Output Frequency Upper Limit
Default: 599.00
Settings 0.00–599.00Hz

Output Frequency Lower Limit
Default: 0.00
Settings 0.00–599.00Hz
 Use the upper and lower limit output frequency settings to limit the actual output frequency. If the
frequency setting is higher than the upper limit (Pr. 01-10), the drive uses the upper limit
frequency. If output frequency is lower than lower limit (Pr. 01-11) and frequency setting is higher
than minimum frequency (Pr. 01-07), the drive uses the lower limit frequency. Set the upper limit
frequency > lower limit frequency (Pr.01-10 setting value must be > Pr.01-11 setting value).
 The upper output frequency limits the maximum output frequency of the drive. If the frequency
setting is higher than Pr.01-10, the Pr. 01-10 setting limits the output frequency.
 When the drive starts the slip compensation function (Pr.07-27) or PID feedback control, the drive
output frequency may exceed frequency command but is still limited by this setting.
