How to use fixed frequencies;
To use fixed frequencies it is necessary to select fixed frequency operation using P1000.
Fixed frequencies can be selected using the digital inputs, and can also be combined with
an ON command.
There are three types of Fixed Frequencies.
1) Direct selection
2) Direct selection + ON command
3) Binary Coded selection + ON command
1. Direct selection (P0701 – P0703 = 15)
In this mode of operation 1 digital input selects 1 fixed frequency. If several inputs are
active together, the selected frequencies are summed. E.g. (FF1 + FF2 + FF3).
Note:
An ON command is also required to start the inverter e.g. from keypad or serial link etc.
2. Direct selection + ON command (P0701 – P0703 = 16)
This fixed frequency selection combines the fixed frequencies with an ON command.
In this mode of operation 1 digital input selects 1 fixed frequency. If several inputs are
active together, the selected frequencies are summed. E.g. (FF1 + FF2 + FF3).
3. Binary Coded Selection + ON command (P0701 – P0703 = 17)
Up to 7 fixed frequencies can be selected using this method. The fixed frequencies are
selected according to the following table:
