Note:
The Safe torque off (STO) safety function is only
implemented in inverter units. Therefore, the STO
function cannot be used in supply, rectifier, DC/DC
converter and brake units. In these units, de-ener-
gizing any connection of STO IN (X52) connector
stops the unit. Note that this stop is not safety re-
lated and must not be used for safety function
purposes.
