Cn-14: Frequency Command Upper Limit

Factory setting:

100

Range: 0 to 109 %

Cn-15: Frequency Command Lower Limit

Factory setting:

Range: 0 to 109 %

These two constants set the range for the frequency command signal. Each is set, in
increments of 1%, as a percentage of maximum frequency (Fmax) 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:

Cn-02 =

60 Hz (100%)

Cn-14 =

80 % = 48Hz – Max. speed

Cn-15 =

10 % = 6Hz – Min. speed

100%

Cn-14 80%
