20.1.1 STO Status
Parameter STO Status 277 can be used for extended diagnosis of the two inputs STOA and STOB.
The statuses of the inputs are shown in bit-encoded form.
Bit
Value
Meaning
0
1
STOA input missing.
1
2
STOB input missing.

FI error (fault).
With correct wiring and correct function, only the 2 states “0” (= STO enabled) and “3” (= STO
disabled) are typically shown (decimal representation) in parameter STO Status 277.
The signal states at digital inputs STOA and STOB can be linked to functions of the frequency
inverter.
292 -
STOA
Signal state at digital input STOA
284 -
STOA inverted
Inverted signal state at digital input STOA
293 -
STOB
Signal state at digital input STOB
285 -
STOB inverted
