Output Frequency Upper Limit

Settings

The upper limit of setting range is the same as Pr. 01-00 maximum operation frequency.
Output Frequency Lower Limit

Settings
 The upper limit of setting range is the same as Pr. 01-00 maximum operation frequency.
 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 the 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
