origin signal of 1-6 feed shaft, and XPLIMn is the positive limit signals of 1-6 feed shafts, and XMLIMn is the
negative limit signal of 1-6 feed shafts.

4.1.2 Wiring Principle of Input Interface
Dc input signals is the signal from machine to CNC, and they come from the side of the machine stop
button, limit switch, proximity switch, relay contact and hand pulse generator gear selector switch, etc. The input
signal for high level effectively, also can for low level effectively. When high level is effective, the system VIN is
connected with 0 v, the public at the input termination is connected with 24 VGND. When low level is effective,
the system VIN is connected with 24 v, the public at the input termination is connected with 24 v. Please choose
connection mode according to the side of the machine output signal source type leakage type.
The signal circuits of switch input is shown in Fig.4-2.
