Setting the inductive voltage drop Ux
You can use this parameter to set the inductive voltage drop. The compen-
sation effect can be rotated by 180° in the display using a plus or minus sign.
If you do not want to use line drop compensation, you have to set the value
0.0 V.
To set the inductive voltage drop Ux, proceed as follows:
ü Select the LDC compensation method.
1. > Parameter > Compensation > Press until the de-
sired parameter is displayed.
ð Ux line drop compensation.
2. Press to highlight the position.
ð The desired position is highlighted and the value can be changed.
3. Press to increase the value or to reduce it.
4. Press .
ð The inductive voltage drop Ux is set.
Z compensation
To keep the voltage constant for the consumer, you can use Z compensation
to activate a current-dependent increase in voltage. Z compensation is not
dependent on the phase angle φ and should only be used for small changes
in phase angle.
You can also define a limit value to avoid excess voltage on the transformer.
