P00.03
Max. output
frequency
Used to set the max. output frequency of
the inverter. It is the basis of frequency
setup and the acceleration/deceleration.
Setting range: P00.04–400.00Hz
50.00Hz
◎
See the figures behind the radix point, the fieldbus ratio value of the max. output frequency
(P00.03) is 100. 100Hz timed by 100 is 10000 and the corresponding hex is 2710H.
