Chapter 12 Description of Parameter SettingsME300

When Fcmd > Fmin and Fcmd < Fstart:
If Flow < Fcmd, drive runs directly by Fcmd.
If Flow ≥ Fcmd, drive runs by Fcmd, then rises to Flow according to acceleration time.
The output frequency goes directly to 0 when decelerating to Fmin.
Output Frequency Upper Limit
Default: 599.00
Settings 0.00–599.00 Hz
Output Frequency Lower Limit
Default: 0.00
Settings 0.00–599.00 Hz
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
drive output frequency may exceed frequency command but is still limited by this setting.

The lower output frequency limits the minimum output frequency of the drive. When the drive
frequency command is lower than this setting, the lower limit of the frequency limits the drive
output frequency.
