Note: The XSTO input only acts as a true Safe torque off input on the inverter control unit.
De-energizing the IN1 and/or IN2 terminals of other units (supply, DC/DC converter, or brake
unit) will stop the unit but not constitute a true safety function.
■ FSO-xx safety functions module connection (X12)
See the user manual of the FSO-xx module. Note that the FSO-xx safety functions module
is not in use in supply, DC/DC converter or brake units.
