Note
The internal safety relay must be energized in order to operate the inverter (see Chapter
"Gating the power semiconductors"). If the option "Safe Torque Off (STO)" is not available,
this circuit function is achieved permanently by inserting jumpers between terminals 1 and 2
of the two connectors X241 and X242.
If the option "Safe Torque Off (STO)" is used, the safety relay is controlled by the two terminals
2 of connectors X241 and X242. The feedback information from the NC contact terminal 3 at
X241 and X242 is evaluated in a higher-level safety control to check the switching state.
