F-52 Minimum Reference
Range:
0 Unit* [-999999.999 - par. P-03]
F-53 Maximum Reference
Range:
1500.000 [par. P-02 - 999999.999]
Unit*
F-54 Reference Function
Option:
[0] * Sum
[1] External/Preset
Shift between external and preset via a command on a digital input.
3.3.7 F-6# References
Parameters to configure drive to add or subtract a fixed value to an input reference.
F-62 Catch up/slow Down Value
Range:
0.00 %* [0.00 - 100.00 %]
F-64 Preset Relative Reference
Range:
0.00 %* [-100.00 - 100.00 %]
46
Function:
Enter the Minimum Reference. The Minimum Reference is the lowest value obtainable by summing all
references.
Minimum Reference is active only when par. F-50 Reference Range is set to Min.- Max. [0].
The Minimum Reference unit matches:
• The choice of configuration in par. H-40 Configuration Mode Configuration Mode: for Speed
closed loop [1], RPM; for Torque [2], Nm.
• The unit selected in par. F-51 Reference/Feedback Unit.
Function:
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 par. H-40 Configuration Mode: for Speed closed loop [1], RPM; for
Torque [2], Nm.
• The unit selected in par. F-50 Reference Range.
Function:
Sums both external and preset reference sources.
Use either the preset or the external reference source.
Function:
Enter a percentage (relative) value to be either added to or deducted from the actual reference for Catch
up or Slow down respectively. If Catch up is selected via one of the digital inputs (par. E-01 Terminal 18
Digital Input to par. E-06 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 (par. E-01 Terminal 18 Digital Input to par.
E-06 Terminal 33 Digital Input), the percentage (relative) value is deducted from the total reference. Obtain
extended functionality with the DigiPot function. See parameter group F-9# Digital Pot-Meter.
Function:
The actual reference, X, is increased or decreased with the percentage Y, set in par. F-64 Preset Relative
Reference. This results in the actual reference Z. Actual reference (X) is the sum of the inputs selected in
par. F-01 Frequency Setting 1, par. C-30 Frequency Command 2, par. C-34 Frequency Command 3 and
par. O-02 Control Word Source.
