Parameter Description
F-52 Minimum Reference
Range: Function:
obtainable by summing all references.
This value defines the lower limit for
both the local and remote reference
depending on the choice in par. F-02
Operation Method.
NOTICE
This parameter is used in open
loop only.
F-53 Maximum Reference
Range: Function:
60.000 [par. F-52 - Enter the Maximum Reference. The
*
999999.999] Maximum Reference is the highest
obtainable by summing all references.
This value defines the upper limit for
both the local and remote reference
depending on the choice in par. F-02
Operation Method.
F-54 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 on a digital input.

F-64 Preset Relative Reference
Range: Function:
0 % [-100 The actual reference, X, is increased or decreased
- with the percentage Y, set in parameter F-64 Preset
*
100 %] Relative Reference. This results in the actual
reference Z. Actual reference (X) is the sum of the
inputs selected in:
•
Parameter F-01 Frequency Setting 1.
•
Parameter C-30 Frequency Command 2.
•
Parameter C-34 Frequency Command 3.
•
Parameter O-02 Control Word Source.

3.2.9 F-9# Digital Potentiometer
The digital potentiometer function allows the user to
increase or decrease the actual reference by adjusting the
set-up of the digital inputs using the functions INCREASE,
DECREASE or CLEAR. To activate the function, at least one
digital input must be set up to INCREASE or DECREASE.

decrease is activated, the resulting reference
is increased or decreased by the value set in
this parameter.
Function:
Enter the ramp time, that is the time for
adjustment of the reference 0–100% of the
specified digital potentiometer function (increase,
decrease, or clear).
If increase/decrease is activated for longer than the
ramp delay period specified in parameter F-95 Accel/
Decel Ramp Delay, the actual reference is acceled/
deceled according to this ramp time. The ramp
time is defined as the time spent to adjust the
reference by the step size specified in
parameter F-90 Step Size.
