<15m shield cable
C N C side
The shield cable must be used between the system and the spindle encoder, and the shield
must be connected with the shell of two-terminal socket.
The output signal of spindle encoder is not in the differential mode, PA-, PB-, PZ- cannot be
connected and the ability of anti-interference is reduced at the moment. It is recommended
that the spindle encoder in differential output mode.
3.4 X4 Tool Post Device Interface
The tool post interface should be connected to the rotation tool post of machine. The system can
adopt the rotation tool post with the tool selections 4-8. When the tools are more than 4, it is input
to CNC by T1-T4 code.

tool post expands one standby input and two standby output interfaces, the two
output interfaces are the three-color indicators of machine. BKO1 is green and BKO2 is red. The
standby input and output interface are different according to the user software.
