If the Upper Limit of Output Frequency is 50Hz and the Maximum Output Frequency is 60Hz, the Maximum Output Frequency will be limited to 50Hz.

If the Lower Limit of Output Frequency is 10Hz, and the Minimum Output Frequency (Pr.1-05) is 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 Limit of Output Frequency (Pr.1-07).

Pr.1-9- 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.”

The acceleration/deceleration time 2 determines the time for the AC drive to acceleration/deceleration from 0Hz to Maximum Output Frequency (Pr.1-00) (acceleration/deceleration time 1 is the default). A Multi-Function Input terminal must be programmed to select acceleration/deceleration time 2 and the terminals must be closed to select acceleration/deceleration time 2. See Pr.4-04 to Pr.4-8-

In the diagram shown below, the acceleration/deceleration time of the AC drive is the time between 0 Hz to Maximum Output Frequency (Pr.1-00). Suppose the Maximum Output Frequency is 60 Hz, start-up frequency (Pr.1-05) is 1.0 Hz, and acceleration/deceleration time is 10 seconds. The actual time for the AC drive to accelerate from start-up to 60 Hz is 9.83 seconds and the deceleration time is also 9.83 seconds.
