Line voltage compensation
Line voltage compensation
Line voltage compensation makes it possible to achieve a balanced output on the power
outputs, even when the voltage deviates from standard values. The function can be switched
on and off by the user.
The compensation factor, or the setpoint, is calculated as follows:
The correction factors for the channels of a POM are calculated using the measured values
of this POM.
Note
For POM4320 Highend connection between phase and neutral conductor:
The standard voltage value is calculated as follows:
Standard voltage value POM4320 = CIM parameter/√3

Behavior of the power outputs
Parameterizable response
The response of the power outputs to an interruption in communication with the higher-level
controller can be defined. The same is true in case the higher-level control sends invalid
data, for example, when the S7 CPU is in Stop. Each individual power output can be
parameterized as follows:
● Power output is "deactivated"
This is the default and ensures "secure response" of the power outputs.
● The power output continues to operate with the most recent valid value.
