STO Status

Parameter
STO Status
The statuses of the inputs are shown in bit-encoded form.
Bit Value
0 1 STOA input missing.
1 2 STOB input missing.
2 4 Switch off STOA input.
3 8 Switch off STOB input.
4 16 Timeout STOA.
5 32 Timeout STOB.
6 64 Diagnosis error.
7 128 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
The signal states at digital inputs STOA and STOB can be linked to functions of the frequency
inverter.
292 - STOA
284 - STOA inverted
293 - STOB
285 - STOB inverted
Refer to Application manual "Safe Torque Off STO".
