5. 2. 3 Setting the output frequency limit
(1) Setting the maximum frequency of the inverter
<FH: Maximum frequency>
Basic parameter
■ Function
Set the maximum value of the frequency output from the inverter.
This frequency is also the criteria of acceleration and deceleration time.
■ Parameter setting
Title Parameter name
FH Maximum frequency
*1 Depending on the setup menu. Refer to [5. 3. 10].
The value of <FH> should be equal or greater than that of <VL>.
■ Guideline for the setting
Set the maximum frequency suited for the rating of the motor and load.
• Set <FH: Maximum frequency> after stopping the inverter. You cannot set it during run.
• When increasing the value of <FH: Maximum frequency>, you should also set the corresponding
Memo
value of <UL: Upper limit frequency> as required. --> Refer to the following "Setting the upper
and lower limits of the output frequency".
