Starting frequency setting (F004)
(1) This frequency is the value the operator must set before the Inverter will give an output.
(2) Mainly use when an operator adjusts the starting torque.
(3) By setting the start frequency higher, direct starting is caused and the starting current
increases.
(4) Therefore an overload is within the restriction range and the inverter has a tendency to trip on
over-current protection

Frequency limit (F005/F205 ~ F006/F206)
z
This function can set a upper and lower limit of the output frequency.
z
Even if a frequency command exceeds the upper and lower limit, the inverter will ignore this
value and stop at the values set.
z
Set first upper limit on setting.
z
Be sure that the upper limit (F005)
≥
lower limit (F006).
z
The upper and lower limit will not operate if 0Hz is set.
