Functions
9.3 Power output control
Non-parameterizable response
The following events always result in deactivation of the power outputs:
● Overtemperature.
● Voltage not within in range from 360 V to 520 V
● Failure of the 24 V supply voltage on the CIM or POM
● Violation of the permissible frequency range for POM4320 Highend
Overvoltage protection
The POM4320 features integrated overvoltage protection, which activates the triac for its
own protection when the permissible supply voltage is exceeded.
Behavior during startup
The power outputs remain "deactivated" until a connection to the higher-level controller has
been established and user data has been transferred.

Power control
Operating principle
With phase control, the setpoint specification does not occur with values between 0% and
100%, but rather as an output value between 0 W and 28,800 W. The output control can be
combined with the control modes half-wave control and phase control as well as with all soft
start options.
If the specified output cannot be reached, an error message is generated. The channel is not
switched off, however.
It is also possible to use fields. You must ensure that the field setpoint value continues to be
given in percent.
