Parameter Descriptions
3-04 Reference Function
Option: Function:
[0] Sum Sums both external and preset reference
*
sources.
[1] External/ Use either the preset or the external
Preset reference source. Shift between external and
preset via a command or a digital input.
4.4.2 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
Range: Function:
0 % [-100 - Enter up to 8 different preset references (0-7)
*
100 %] in this parameter, using array programming.
Select preset reference bit 0/1/2 [16], [17], or [18]
for the corresponding digital inputs in
parameter group 5-1* Digital Inputs, for
selecting dedicated references.
3-11 Jog Speed [Hz]
Range: Function:
5 Hz [ 0 - 400.0 The jog speed is a fixed output speed which
*
Hz] 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 catching up or slowing down respectively. If
[28] Catch up is selected via one of the digital
inputs (parameter 5-10 Terminal 18 Digital Input to
parameter 5-15 Terminal 33 Digital Input), the
percentage (relative) value is added to the total
reference. If [29] Slow down is selected via one of
the digital inputs (parameter 5-10 Terminal 18
Digital Input to parameter 5-15 Terminal 33 Digital
Input), the percentage (relative) value is deducted
from the total reference.
3-14 Preset Relative Reference
Range: Function:
0 % [-100 - The actual reference, X, is increased or decreased
*
100 %] with the percentage Y, set in
parameter 3-14 Preset Relative Reference. This
results in the actual reference Z. Actual reference
(X) is the sum of the inputs selected in
parameter 3-15 Reference 1 Source,
parameter 3-16 Reference 2 Source,

Function:
Select the reference input to be used
for the first reference signal.
Parameter 3-15 Reference 1 Source,
parameter 3-16 Reference 2 Source, and
parameter 3-17 Reference 3 Source define
up to 3 different reference signals. The
sum of these reference signals defines
the actual reference.
