4–63
Upper Bound of Output Frequency Default Setting: 400
Range: 0.1 to 400 Hz
• The Upper/Lower Bound of Output Frequency is to prevent operation error and
machine damage.
• This parameter must be equal to or greater than the Lower Bound of Output
Frequency (P6.16).
• If the Upper Bound of Output Frequency is 50Hz and the Maximum Output
Frequency is 60 Hz, then any Command Frequency above 50 Hz will generate a
50 Hz output from the drive.
• The Output Frequency is also limited by the Motor Maximum RPM (P0.04).
Lower Bound of Output Frequency Default Setting: 0.0
Range: 0.0 to 400 Hz
• The Upper/Lower Bound of Output Frequency is to prevent operation error and
machine damage.
• This parameter must be equal to or less than the Upper Bound of Output
Frequency (P6.15).
• If the Lower Bound of Output Frequency is 10 Hz, and the Minimum Output
Frequency (P2.06) is set at 1.0 Hz, then any Command Frequency between 1-10
Hz will generate a 10 Hz output from the drive.
• The Upper/Lower Bound of Output Frequency is to prevent operation error and
machine damage.
If the reference frequency is less than 0.5 Hz, then this parameter setting is disabled.
