5.4.4 Using the fixed frequency as a setpoint source
Frequency setpoint via fixed frequency (P1000 = 3)
The fixed frequencies are defined using parameters P1001 to P1004 and can be assigned to
the corresponding digital inputs using P1020 to P1023.
Parameter Description
P1016 = 1 Fixed frequency mode,
defines the procedure
for selecting fixed
frequencies.
1: Direct selection
(factory setting)
2: Binary-coded
selection
P1001 = 0 Fixed frequency 1 (FF1)
(FF values in Hz)
P1002 = 5 Fixed frequency 2
((FF2)
P1003 = 10 Fixed frequency 3 (FF3)
P1004 = 15 Fixed frequency 4 (FF4)
P1020 = 722.3 FF1 selection using DI3
P1021 = 722.4 FF2 selection using DI4
P1022 = 722.5 FF3 selection using DI5
P1023 = 722.6 FF4 selection using DI6
The fixed frequency can be selected using four digital
inputs (factory setting: DI3 … DI6) and combined (e.g.
summed). The factory settings support the following
additional combinations:
