④ Transition to STO
• SBR ends as soon as the actual speed value is below the STO
switch-o speed (p9560).
• The converter activates STO.
• The converter activates STO even if SS1 is deselected in the
meantime.
• The converter signals the status "STO active" (r9722.0).
• STO interrupts the torque-generating supply of energy to the
motor and prevents the motor from unexpectedly restarting.
• The motor coasts down to a standstill.
⑤ Deselection of SS1
• The converter detects deselection of SS1.
• The converter deactivates STO.
⑥ Signal change at ON/OFF1
from 1 to 0
• The converter is ready to start again.
⑦ Signal change at ON/OFF1
from 0 to 1
• The motor starts again.
