2-17 Over-voltage Control
Option:
Function:
Overvoltage control (OVC) reduces
the risk of the frequency converter
tripping due to an overvoltage on
the DC-link caused by generative
power from the load.
[0]
*
Disabled
No OVC required.
[1]
Enabled (not
at stop)
Activates OVC except when using a
stop signal to stop the frequency
converter.
[2]
Enabled
Activates OVC.
NOTICE
Do not enable OVC in hoisting applications.
2-19 Over-voltage Gain
Range:
Function:
100 %
*
[10 - 200 %]
Select overvoltage gain.
4.4 Parameters: 3-** Reference/Ramps
Parameters for handling of reference, definition of
limitations, and configuration of the reaction of the
frequency converter to changes.
4.4.1 3-0* Reference Limits
3-00 Reference Range
Option:
Function:
Select the range of the reference
signal and the feedback signal.
Signal values can be positive only,
or positive and negative. The
minimum limit may have a negative
value, unless
[1] Speed closed loop
control or
[3] Process
is selected in
parameter 1-00 Configuration Mode
.
[0]
Min - Max
Select the range of the reference
signal and the feedback signal.
Signal values can be positive only,
or positive and negative. The
minimum limit may have a negative
value, unless
[1] Speed closed loop
control or
[3] Process
is selected in
parameter 1-00 Configuration Mode
.
[1]
-Max - +Max
For both positive and negative
values (both directions, relative to
parameter 4-10 Motor Speed
Direction
).
3-01 Reference/Feedback Unit
