Deactivation of STO
When both
STO1
and
STO2
inputs are high it means that the STO is
deactivated and that the motor can rotate / produce torque.
To activate STO both STO-inputs shall be disconnected from 24Vdc supply
voltage simultaneously. The unsafe ‘STO_STATUS_ISO’ output is available to
diagnose the safety channel wiring as well as the actual gate driver status.
Upon detecting fault in electronics of OSTO_100 option e.g. incorrect voltage
level on PCB, the STO will be activated (safe state).
