Using fixed frequencies 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.
The fixed frequency can be selected using digital input 3 by default. However, the
assignment of fixed frequencies can be configured to use any of the other digital inputs on
the Inverter. An example is given below of selecting two fixed frequencies using digital input
2 and 3.

Parameters
P1016 = 1
P1001 = 50
P1002 = -50
P1003 = 10
P1004 = 15
P1020 = 2091.0
Additional information about binary coded selection of the fixed frequencies (P1016 = 2) is
provided in function chart 3210 of the List Manual.

Parameters to directly select frequencies
Description
Fixed frequency mode, defines the procedure for selecting fixed frequencies.
1: Direct selection (factory setting)
2: Binary-coded selection
Fixed frequency 1 (FF1) (FF values in Hz)
Fixed frequency 2 (FF2)
Fixed frequency 3 (FF3)
Fixed frequency 4 (FF4)
FF1 selection using fieldbus
Example: Selecting 2 fixed frequencies using digital input 2 and digital input 3
Description
Enable expert access to parameters
Selecting the command source: Digital inputs
ON/OFF1 (DI0) - factory setting
Direction reversal (DI1) - factory setting
Enable / 'open' digital input 2 (DI2)
Enable / 'open' digital input 3 (DI3)
Defines fixed frequency 1 (FF1) in [Hz]
Defines fixed frequency 2 (FF2) in [Hz]
Connect fixed frequency 1(FF1) with the status of DI2.
2091.0 = Parameter, which displays the status of digital input 2.
Connect fixed frequency 2(FF2) with the status of DI3.
2091.1 = Parameter, which displays the status of digital input 3.
