P: Active power
in % during reduction.
Note:
With a programmable voltage threshold
with programmable P range, the inverter can
activate the active power response to
overvoltage.
The <Settings for> menu is opened.
1.
Select the <P(U) settings>.
2. Select mode > see note below.
3. Define voltage range.
4. Define relative power reduction.
5. Set internal delay time P(U).
6. Define min. delay time for power
reduction.
7. Define power gradient after resetting the
frequency.
» P(U) defined.
Note:
The following 4 modes are available for
selection:

Set the P(U) parameters
1. Fix gradient and non-
hysteresis: ∆P is the
active power as a percentage of Pn; the inverter
provides non-hysteresis in the control of active
power response to overvoltage.
2. Variable gradient and non-
hysteresis: ∆P is
the active power as a percentage of the PM; the
inverter provides non-hysteresis in the control
of active power response to overvoltage.
3. Fix gradient and hysteresis: ∆P is the active
power as a percentage of Pn; the inverter
provides hysteresis in the control of active
power response to overvoltage.
4. Variable gradient and hysteresis: ∆P is the
active power as a percentage of the PM; the
inverter provides hysteresis in the control of
active power response to overvoltage.
Note:
The intentional delay time for P(U) is only
used for the activation of the function in
accordance with the voltage via Ustart, whereby
the intentional delay time plus own dead time
must be smaller than 2s.
Note:
The minimum delay time for enabling of
the active power is the delay time during which
the active power can increase once the voltage
has fallen below Ureset.
