n033 : Frequency Reference Upper Limit Factory setting: 100 %
Range: 0 to 110 %
n034 : Frequency Reference Lower Limit Factory setting: 0 %
Range: 0 to 110 %
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%)
n033 = " 80 " % = 48Hz – Max. speed
n034 = " 10 " % = 6Hz – Min. speed
NOTE: n033 must be set to a higher value than n034.
