There is a diagnostic failure in
the STO safety function. This
fault occurs when the STO
inputs are in a different state for
more than 500 ms.
• Restart the drive.
• If the restart does not help,
check the wiring: Both STO
input channels of OPTBJ need
to be on the same state, i.e.
safety device controlling the
inputs needs to feed or cut
power from both STO1
and STO2
channels simultaneously.
• If the inputs are on the same
state and the fault re-occurs,
replace the OPTBJ board.
