teresis)
Description
Time constant (1 Tau) in
seconds [s]. Whenever the
set value is changed, this
new set value is not
triggered abruptly, but
smoothly in accordance
with a PT1 response. The
time constant describes
how quickly the new set
value is reached. (After
three time constants the
final value 95 % is
reached)
Mains voltage limit value
up to which the power re-
duction takes place. The
gradient is automatically
calculated from the para-
meters "Activation
Threshold Overvoltage"
and "Power at Stop
Voltage at Overvoltage".
The parameters "Gradient
Overvoltage" and "Calcula-
tion Mode" have no func-
tion.
Reference power when the
set mains voltage limit
value is reached.
Description of the parameters
(1) "Activation Threshold Overvoltage":
250 V
(2) "Stop at Voltage at Overvoltage":
260 V
(3) "Power at Stop Voltage - Overvoltage":
20 %
