3-04 Reference Function
Option:
Function:
[0]
*
Sum
Sums both external and preset reference
sources.
[1]
External/
Preset
Use either the preset or the external
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 -
100 %]
Enter up to 8 different preset references (0-7)
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
Hz]
The jog speed is a fixed output speed which
the frequency converter is running when the
jog function is activated. See also
.
3-12 Catch up/slow Down Value
Range:
Function:
0 %
*
[0 -
100 %]
Enter a percentage (relative) value to be either
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 (
to
parameter 5-15 Terminal 33 Digital
), the percentage (relative) value is deducted
from the total reference.
3-14 Preset Relative Reference
Range:
Function:
0 %
*
[-100 -
100 %]
The actual reference, X, is increased or decreased
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
,

Option:
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.
