Enter the Maximum Reference. The
Maximum Reference is the highest
value obtainable by summing all
references.
The Maximum Reference unit
matches:
•
The choice of configu-
ration in
1-00 Configuration Mode:
for [1] Speed closed loop,
RPM; for [2] Torque, Nm.
•
The unit selected in
3-00 Reference Range.
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.
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*.

[-100.00 -
100.00 %]
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
MAX
(3-03 Maximum Reference) If a Ref
MIN
different from 0 (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
MAX
and Ref
MIN
.
Afterwards, the value is added to Ref
MIN
.
When using preset references, select Preset
ref. bit 0/1/2 [16], [17] or [18] for the
corresponding digital inputs in parameter
group 5-1*.

The jog speed is a fixed output
speed at which the frequency
converter is running when the jog
function is activated.

%*
[0.00 -
100.00 %]
Enter a percentage (relative) value to be
either added to or deducted from the actual
reference for Catch up or Slow down respec-
tively. 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. See parameter group
3-9* Digital Potentiometer.
