FC 300 Design Guide
Minimum Reference is active only when par. 3-00
Reference Range is set to Min.- Max. [0].
The Minimum Reference unit matches
- the choice of configuration in par 1-00 Configu-
ration Mode: for Speed closed loop [1], RPM; for
Torque [2], Nm.
- the unit selected in par. 3-01 Reference/Feed-
back Unit.
3-03 Maximum Reference
Value:
Par. 3-02 - 100000.000
Function:
Enter the Maximum Reference. The Maximum
Reference is the highest value obtainable by sum-
ming all references. The Maximum Reference unit
matches
- the choice of configuration in par. 1-00 Config-
uration Mode: for Speed closed loop [1], RPM; for
Torque [2], Nm.
- the unit selected in par. 3-01 Reference/Feed-
back Unit.
3-04 Reference Function
Value:
Sum
External/Preset
Function:
Select Sum [0] to sum both external and preset
reference sources.
Select External/Preset [1] to use either the preset
or the external reference source.
Shift between external and preset via a command
on a digital input.
3-1* References
Parameters for setting up the reference sources.
Select the preset reference(s). Select Preset ref.
bit 0 / 1 / 2 [16], [17] or [18] for the correspond-
ing digital inputs in parameter group 5.1* Digital
Inputs.

MG.33.B7.02 - VLT is a registered Danfoss trademark
Function:
Enter up to eight different preset references (0-7)
in this parameter, using array programming. The
preset reference is stated as a percentage of the
value Ref (par. 3-03 Maximum Reference) If a
MAX
Ref different from 0 (Par. 3-02 Minimum Ref-
MIN
erence) 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
MAX MIN
to 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]
Value:
0.0 - par. 4-14
Function:
The jog speed is a fixed output speed at which the
frequency converter is running when the jog func-
tion is activated.
See also par. 3-80.
3-12 Catch up/slow Down Value
Value:
0.00 - 100.00%
Function:
Enter a percentage (relative) value to be either
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 (par. 5-10 to
par. 5-15), the percentage (relative) value is add-
ed to the total reference. If Slow down is selected
via one of the digital inputs (par. 5-10 to par.
5-15), the percentage (relative) value is deducted
value for use in communication via serial communication port
. Afterwards, the value is added
