frequency
Used to set the max. output frequency of
the VFD. Pay attention to the function
code because it is the foundation of the
frequency setting and the speed of
acceleration (ACC) and deceleration
(DEC).
Setting range: P00.04–400.00Hz

According to the number of decimals, the fieldbus scale of the "Max. output frequency"
(P00.03) is 100. Multiply 100 Hz by 100. The value 10000 is obtained, and it is 2710H in
the hexadecimal form.
