Danfoss FC302

Dear All

I want to use Danfoss fc 302 Preset Refrence .can anybody guide me on this ...thanks in advance

The manual http://www.danfoss.com/NR/rdonlyres/7A26C400-E12C-4A88-BEB7-78FD089D6D9A/0/09_12_MG33MF02.pdf says:

Preset reference is used when setting a predefined reference for the drive. The FC 302 has 8 preset reference points (Par. 3-10.0....3-10.7).

The Preset references are selectable from digital inputs, but you need to set up the inputs you want to use (Par. 5-1x). 3 bits a possible (Preset ref bit 0, 1 and 2).

If you set Terminal 18, 19 and 29 to those respectively this is what you'll get:

T18 T19 T29
0 0 0 = Preset Reference 0 (Par. 3-10.0)
1 0 0 = Preset Reference 1 (Par. 3-10.1)
0 1 0 = Preset Reference 2 (Par. 3-10.2)
1 1 0 = Preset Reference 3 (Par. 3-10.3)
0 0 1 = Preset Reference 4 (Par. 3-10.4)

And so on (sory the layout of the forum does not permit me to space the way I wanted to)

If you are using a bus system, I'd not bother with preset references but rather make that in my PLC and just use the reference word to send it to the drive.
