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
Option: Function:
Select the unit to be used in
process PID control references and
feedbacks.
