Parameter Descriptions
3-03 Maximum Reference
Range: Function:
Size [ par. 3-02 - Enter the Maximum Reference. The
related 999999.999 Maximum Reference is the highest
*
ReferenceFeed- value obtainable by summing all
backUnit] references.

3-04 Reference Function
Option: Function:
[0] Sum Sums both external and preset reference
sources.
[1] External/ Use either the preset or the external reference
Preset source.
Shift between external and preset via a
command or a digital input.
3.5.2 3-1* References
Select the preset reference(s). Select Preset ref. bit 0/1/2
[16], [17] or [18] for the corresponding digital inputs in
parameter group 5-1* Digital Inputs.
3-10 Preset Reference
Array [8]
Range: 0-7
Range: Function:
0 % [-100 - Enter up to 8 different preset references (0-7) in
*
100 %] this parameter, using array programming. The
preset reference is stated as a percentage of the
value Ref (parameter 3-03 Maximum Reference)
MAX
If a Ref different from 0
MIN
(parameter 3-02 Minimum Reference) is
programmed, the preset reference is calculated
as a percentage of the full reference range, i.e.
on the basis of the difference between Ref
and Ref . Afterwards, the value is added to
MIN
Ref . When using preset references, select
MIN
Preset ref. 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:
Size [ 0 - par. The jog speed is a fixed output speed
related 4-14 Hz] at which the frequency converter is
*
running, when the jog function is
activated.
See also parameter 3-80 Jog Ramp Time.
3-12 Catch up/slow Down Value
Range: Function:
0 % [0 - Enter a percentage (relative) value to be either
*
100 %] added to or deducted from the actual reference
for Catch up or Slow down respectively. If Catch
up is selected via one of the digital inputs
(5-10 Terminal 18 Digital Input to 5-15 Terminal 33
Digital Input), the percentage (relative) value is
added to the total reference. If Slow down is
selected via one of the digital inputs
(5-10 Terminal 18 Digital Input to 5-15 Terminal 33
Digital Input), the percentage (relative) value is
deducted from the total reference. Obtain
extended functionality with the DigiPot function.
