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