9.3.1 Mains monitoring (LP0, LP1)
Mains voltage and mains frequency (LP0)
Mains voltage and mains frequency are permanently measured. The permissible ranges
depend on the mains voltage set under C0173. The mains frequency must be within the
range from 45 to 66 Hz. If the measured values are not within these limits, an LP0 message
is activated and the DC bus cannot be charged or is disconnected from the mains.
If the power supply module is ready for operation, the limits are expanded to tolerate short
mains fluctuations. In this case, an LP0 warning is displayed.
When C0173 = 4 (automatic detection of the mains voltage), the range is defined with the
rising edge of the mains enable input.
