Connection examples of two-wire and three-wire sensors

The figures give examples of connections for a two-wire or three-wire
sensor/transmitter that is supplied by the auxiliary voltage output of the drive.

Safe torque off

For the drive to start, both STO connections (S+ to S1 and S+ to S2) must be closed.
By default, the terminal block has jumpers to close the circuit. Remove the jumpers
before connecting external Safe torque off circuitry to the drive. See chapter
Safe torque off function.

Communication mode jumper J2

The drive with below hardware revision doesn't have J2, and does not need to
switch between panel and Modbus mode.
