Limit switches

The UCC T3 controller supports both inner and outer limit switches for all directions of machine axes. During the commissioning process it is
possible to invert this signal from an active low signal to an active high. If this capability is not required for integration to the system, then it
should be connected to the 0 V (24 V return line).
Inner limit switches
If an inner limit is activated, the UCC T3 system will perform a maximum movement deceleration in all axes to a stop and then perform a
controlled axis back-off in the opposite direction as if a trigger event occurred.
Outer limit switches
If an outer limit is activated the UCC T3 system will immediately disengage all servo power to the machine drives. Recovery of this error is
only possible by removing the outer limit switch activation, i.e. by moving the machine off the switch.
0 V (24 V return)
This is the 0 V reference for all the I / O signals.
