413 Overmodulation function
(OVERMODUL)
Value:
Off (OFF)
[0]
✭On (ON)
[1]
Function:
This parameter allows connection of the
overmodulation function for the output voltage.
Description of choice:
Off means that there is no overmodulation of the
output voltage, which means that torque ripple on
the motor shaft is avoided. This can be a good
feature, e.g. on grinding machines.
On means that an output voltage can be obtained
which is greater than the mains voltage (up to 15%).
414 Minimum feedback
(MIN. FEEDBACK)
Value:
-100,000.000 - Max. feedback
✭ 0.000
Function:
Parameters 414 and 415 are used to scale the display
text to make it show the feedback signal as the actual
unit proportional to the signal on the input. This value
will be displayed if Feedback [unit] [3] has been selected
in one of parameters 009-012 and in the display mode.
Choose the feedback signal unit in parameter 416.
Used together with Speed control, closed loop;
Process control, closed loop and Torque control
speed feedback, (parameter 100).
Description of choice:
Is only active when parameter 203 has been
set to Min-Max [0].
Setthevaluetobeshownonthedisplaywhen
Minimum feedback is obtained on the selected
feedback input (parameter 308 or 314).
The minimum value can be limited by the choice of
configuration (parameter 100) and reference/feedback
range (parameter 203).
If Speed control, closed loop [1] has been
selected in parameter 100, minimum feedback
cannot be set under 0.
415 Maximum feedback
(MAX. FEEDBACK)
Value:
Min. feedback - 100,000.000
✭ 1,500.000
Function:
This value should be 10% higher than par. 205
Maximum reference, to keep the frequency converter
from integrating as a response to a possible offset fault.
For further description, see parameter 414.
Description of choice:
Setthevaluetobeshownonthedisplaywhen
Maximum feedback is obtained on the selected
feedback input (parameter 308 or 314).The
maximum value can be limited by the choice of
configuration (parameter 100).
