Danfoss VLT CDS 803 Programming Guide

3-10 Preset Reference
Range: Function:
selecting dedicated references,
select preset reference bit 0/1/2 [16],
[17], or [18] for the corresponding
digital inputs in parameter group
5-1* Digital Inputs.
3-11 Jog Speed [Hz]
Range: Function:
30 Hz* [ 0 - 500.0
Hz]
The jog speed is a xed output
speed at which the frequency
converter is running when the jog
function is activated.
See also parameter 3-80 Jog Ramp
Time.
3-14 Preset Relative Reference
Dene the xed value in %.
Range: Function:
0 %* [-100 -
100 %]
The sum of xed and variable
values (labeled Y in Illustration 3.3)
is multiplied by actual reference
(labeled X in Illustration 3.3). This
product is added to actual
reference X + X × 

3-15 Reference 1 Source
Select the input to be used for the 1
st
reference signal.
Parameter 3-15 Reference 1 Source, parameter 3-16 Reference 2
Source, and parameter 3-17 Reference 3 Source dene up to 3
dierent reference signals. The sum of these reference signals
denes the actual reference.
