3-03 Maximum Reference
Range: Function:
Application
dependent
*
[Application
dependant] Enter the Maximum Reference. The
Maximum Reference is the highest
value obtainable by summing all
references.
The Maximum Reference unit
matches:
•
The choice of configuration
in
1-00 Configuration Mode :
for Speed closed loop [1],
RPM; for Torque [2], 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 on 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*.
3-10 Preset Reference
Array [8]
Range: 0-7
Range: Function:
0.00
%
*
[-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*.

3-11 Jog Speed [Hz]
Range: Function:
Application
dependent
*
[Application
dependant] The jog speed is a fixed output
speed at which the frequency
converter is running when the
jog function is activated.

3-12 Catch up/slow Down Value
Range: Function:
0.00
%
*
[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 .
