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 -
999999.999]
Enter the Maximum Reference. The
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/
Preset
Use either the preset or the external
reference source.
Shift between external and preset via a
command on a digital input.
3.2.8 F-6# References
F-64 Preset Relative Reference
Range:
Function:
0 %
*
[-100
-
100 %]
The actual reference, X, is increased or decreased
with the percentage Y, set in
. 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.
F-90 Step Size
Range:
Function:
0.10 %
*
[0.01 -
200 %]
Enter the increment size required for
increase/decrease as a percentage of the
synchronous motor speed, n
s
. If increase/
decrease is activated, the resulting reference
is increased or decreased by the value set in
this parameter.
F-91 Accel/Decel Time
Range:
Function:
1 s [0 -
3600 s]
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
, 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
F-92 Power Restore
Option:
Function:
[0]
*
Off
Resets the digital pot-meter reference to 0% after
power-up.
[1]
On
Restores the most recent digital pot-meter reference at
power-up.
