XPCI1C00 motion control card origin switch signal input circuit:
2.
specialized input: alarm switch signal
Generally, there is one alarm signal output, and this signal can be read through
XPCI1C00.
3.
specialized input: position limit switch signal
In the motion system, one position sensor is usually used to set a mechanical limit
point to determine the boundary position of the motion and protect the mechanical
equipment.
Each axis of XPCI1C00 has two position limit signal input ports +EL and -EL. +EL is
positive limit signal, -EL is negative limit signal.
The limit switch signal input circuit diagram is shown in the figure.
