Overview of the [X3] interface
Figure 118: Position of connector X3
At its front, the servo drive has an 8-pin connector [X3] for
l
the STO control inputs,
l
the digital output DOUT0, and
l
the digital inputs DIN 6 and DIN 7
The STO safety function is requested exclusively via the two digital control inputs STOA
and STOB. The safety-oriented integration of additional interfaces is not
necessary/intended.
The servo drive does not monitor the input circuit for cross-circuit faults.
The [X3] interface enables the direct connection of active and passive sensors as
DOUT0/GND provide a short-circuit-proof 24 V supply voltage (see section 13.12
