Function:
[0 - 100 %] Enter a percentage (relative) value
to be either added to or deducted
from the actual reference for catch
up or slow down. If catch up is
selected via 1 of the digital inputs
(parameter 5-10 Terminal 18 Digital
Input to parameter 5-15 Terminal 33
Digital Input), the percentage
(relative) value is added to the total
reference. If slow down is selected
via 1 of the digital inputs
(parameter 5-10 Terminal 18 Digital
Input to parameter 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.
Function:
Select which reference site to activate.
Use local reference when in hand-on mode,
or remote reference when in auto-on mode.
Use remote reference in both hand-on mode
and auto-on mode.
Use local reference in both hand-on mode
and auto-on mode.
NOTICE
When set to [2] Local, the frequency
converter starts with this setting again
after a power-down.
Function:
[-200 - The actual reference, X, is increased
or decreased with the percentage Y,
set in parameter 3-14 Preset Relative
Reference.
This results in the actual reference
Z. Actual reference (X) is the sum of
the inputs selected in:
•
Parameter 3-15 Reference 1
Source.
•
Parameter 3-16 Reference 2
Source.
•
Parameter 3-17 Reference 3
Source.
•
Parameter 8-02 Control
