Range
= 00.50/400.0
Factory Setting = 400.0
This parameter sets the highest frequency or speed that the drive can be set
to by any input control signal, unless Parameter 15 (Maximum Frequency)
or Parameter 3 (Frequency Range) has been set lower. If set to a value
higher than Parameter 3 or 15, the value will be entered, but the drive will
default to the lowest value set by Parameter 3 or 15 when operating.
From 00.50-100.0 Hz, Parameter 51 sets the Upper Frequency Clamp in
.01 Hz increments.
From 100.0-400.0 Hz, Parameter 51 sets the Upper Frequency Clamp in
0.1 Hz increments.
