n031 : Frequency Reference Upper Limit Factory setting: 100 %
(Ref Upper Limit) Range: 0 to 109 %
n032 : Frequency Reference Lower Limit Factory setting: 0 %
(Ref Lower Limit) Range: 0 to 100 %
These two parameters set the range for the frequency command signal. Each is set, in
increments of 1%, as a percentage of maximum frequency (Fmax; n011) as established
by either the selected standard V/f pattern or custom V/f pattern.
NOTE: All references are affected by the upper and lower limit points.
EXAMPLE:
n011 = " 60 " Hz (100%)
n031 = " 80 " % = 48Hz – Max. speed
n032 = " 10 " % = 6Hz – Min. speed
