9.2.1 Monitoring functions - explanations
Mains
voltage
Warning:
This monitoring function checks, if the mains voltage has a value within the adjusted volt-
age range. If the value is lower than the set value in P1354, the warning „mains under-
voltage“ is generated. If the value is higher than the set value in P1355, the warning
„mains overvoltage“ is generated.
Error:
If the value is lower than an intern set value, the error „mains undervoltage“ is generated.
If the value is higher than an intern set value, the error „mains overvoltage“ is generated.
In released status an immediate pulse inhibit result from an error message mains over-
voltage or mains undervoltage.
Phase
monitoring
This monitoring function checks the three phases of the mains voltage. If an outer con-
ductor is missing, the warning „Phase failure“ is reported.
If all three phases are missing, the warning „mains failure“ is indicated to the controller.
Mains frequency
monitoring This monitoring function checks the following:
n
If the mains frequency value is within the permissible frequency range. If the value is
lower or higher the controller generates an error message „Frequency range error“ and
an immediate pulse inhibit occurs.
n
If the mains frequency change is too high. If the mains frequency change is > 5 Hz/s
the controller generates an error message „Frequency change error“ and immediately
a pulse inhibit occurs.
