Electrical installation

5.2.4.1 Digital inputs X15, X25
With the AX8911 TwinSAFE drive option installed, the inputs X15 (axis "A") and X25 (axis "B") are used for
the STO inputs of the axis or axes.
Contacts 1 and 2 of the connection X15 are the STO inputs for axis "A". Axis "A" can be moved if both
signals are logic 1 (24 V
torque-free.
Contacts 1 and 2 of the connection X25 are the STO inputs for axis "B". Axis "B" can be moved if both
signals are logic 1 (24 V
torque-free.
Fig. 1: AX8911: Connection to X15 and X25
A plug connector is required in each case to connect signals to X15 and, in the case of two-channel axis
modules, to X25 also.
