5.1.8 DRV-19 Start Frequency
The inverter output frequency can be limited by setting Start and Maximum frequencies. These include
start frequency, maximum frequency, upper and lower frequency limits. Refer to 5.4.7 ADV-24
Frequency Limits - Upper/Lower Limit Frequency on page 147 for details on frequency limits.
5.1.8.1 Frequency Limit Using Max. Frequency and Start Frequency
40.00–400.00 240V, 480V
40.00-120.00 575V
40.00-120.00 IM SVC
40.00-180.00 PM SVC
Frequency Limit Using Maximum Frequency and Start Frequency - Setting Details
Sets the start frequency. A start frequency is a frequency at which the
inverter starts voltage output. The inverter does not produce output voltage
while the frequency reference is lower than the set frequency. However, if a
deceleration stop is made while operating above the start frequency, output
voltage will continue until the operation frequency reaches a full-stop (0 Hz).
If the reference frequency is lower than the start frequency, the parameter
value will be 0.00.
All frequency selections are restricted to frequencies within the Start and
Max limits. This restriction also applies when you in input a frequency
reference using the keypad.
5.1.9 DRV-21 Changing the Displayed Units (Hz-Rpm)
You can change the units used to display the operational speed of the inverter by setting DRV- 21
(Speed unit selection) to 0 (Hz Display) or 1 (Rpm Display).
5.1.10 DRV-30 Changing the Displayed Units (kW/HP)
You can change the units used to display the inverter and motor capacity by setting DRV- 30 (kW/HP
Unit Sel) to 0 (kW Display) or 1 (HP Display).
