DC1 Frequency Inverter 10/12 MN04020003Z-EN www.eaton.com 125
6.2.9 Fixed frequency setpoint values
Fixed frequency reference values have a higher priority than other frequency
reference values. They can be accessed individually, or in binary code, via
digital inputs DI1 to DI4.
6.2.9.1 Fixed frequency
Four different fixed frequency reference values can be set in parameters
P-20 to P-23 (FF1 to FF4).
In the default settings, fixed frequency FF1 = 15 Hz can be accessed via
digital input DI3 (control signal terminal 4).
Figure 73: Example: fixed frequencies FF1 to FF4
￫
The maximum permitted set value for a fixed frequency is lim-
ited by parameter P-01 (maximum frequency).
A fixed frequency value cannot go below a minimum limit fre-
quency set at parameter P-02.
If a fixed frequency is lower than the minimum frequency (P-02),
the DC1 frequency inverter will move to the minimum fre-
quency.
￫
The fixed frequency values can be changed during operation
(RUN).
