1 - 08 Lower Bound of Output Frequency Factory Setting: d 0
Settings d 0 to d100% Unit: 1%
& The Upper/Lower Bound is to prevent operation error and machine damage.
& If the Upper Bound of Output Frequency is 50Hz and the Maximum Output
Frequency is 60Hz, the Maximum Output Frequency will be limited to 50Hz.
& If the Lower Bound of Output Frequency is 10Hz, and the Minimum Output
Frequency Pr.1-05is set at 1.0Hz, then any Command Frequency
between 1-10Hz will generate a 10Hz output from the drive.
& This parameter must be equal to or less than the Upper Bound of Output
Frequency (Pr.1-07).
1 - 09 Acceleration Time 1 (Taccel 1) Factory Setting : d10.0
1 - 10 Deceleration Time 1 (Tdecel 1) Factory Setting : d10.0
1 - 11 Acceleration Time 2 (Taccel 2) Factory Setting : d10.0
1 - 12 Deceleration Time 2 (Tdecel 2) Factory Setting : d10.0
Settings d 0.1 to d 600Sec Unit: 0.1Sec
These parameters can be set during operation.
& Pr.1-09. This parameter is used to determine the time required for the AC
drive to ramp from 0 Hz to its Maximum Output Frequency (Pr.1-00). The
rate is linear unless S-Curve is “Enabled.”
& Pr.1-10. This parameter is used to determine the time required for the AC
drive to decelerate from the Maximum Output Frequency (Pr.1-00) down to 0
Hz. The rate is linear unless S-Curve is “Enabled.”
