130.35 Mains failure detection mode
A mains failure is normally detected by the supply unit.
This detection is not fast enough for specific applications. Therefore the DC link voltage
can be additionally used to determine a mains failure.
Bit no. Meaning
0 0: No error
1: Timeout.
No update of the status word within the last two seconds.
Bits 5 ... 7 and bits 13 ... 15 are not valid
1 1: CRC error at latest transfer of the status word
4 ... 2 Reserved
5 0: No error
1: Error at internal communication in STO module
6 0: No error
1: Internal diagnosis channel 2 has triggered STO
7 0: No error
1: Internal diagnosis channel 1 has triggered STO
12 ... 8 Reserved
13 0: No error
1: Initialization error in STO module
14 0: Input terminal channel 2 is powered with 24 V
1: No 24 V power supply at input terminal of channel 2
15 0: Input terminal channel 1 is powered with 24 V
1: No 24 V power supply at input terminal of channel 1
Value Meaning Remark
0 Mains failure detection via
the supply unit
A mains failure is detected in the supply unit by
means of the mains.
1 Mains failure detection
additionally via DC link volt
-
age (relative threshold).
The nominal value of the DC link voltage is
determined after switch on of mains. The
adjustable threshold (
Z130.36–) is related to
this value.
As soon as the DC link voltage falls below this
threshold, this is regarded as mains failure.
2 Mains failure detection
additionally via DC link volt
-
age (absolute threshold).
As soon as the DC link voltage falls below the
threshold set in
Z130.37–, this is regarded as
mains failure.
