The above process is for preliminary debugging, see below for detailed steps:
1) Connect the Lambda controller to the communication card or NC65A/65B host with a DB9M/F cable,
provide 24V power supply for the controller, check whether the power indicator on the controller is
on, and power on the machine signal system (proximity switch, etc). If the home switches connected
are normally closed, at this time, three LEDs of X0, Y0 and Z0 should be on. Trigger a home switch
through artificial imitation. (For a travel switch, artificial press can be used to observe whether the
signals can be received. For a photoelectrical switch, artificially obstruct the light to see if the signals
can be gotten. For a metal proximity switch, artificially approach it with a metal block to see if the
signals can be gotten.) If the corresponding LED is out, it indicates the REF. point signals have been
sent to the controller. If the home switches connected are normally open, LEDs should be usually
out, and by artificially touching a switch, the LED should light, which shows the REF. point signals
have been sent to the controller. The same method can be taken to test other input ports to ensure
the correctness of the wiring between the controller and the machine tool, to greatly shorten the
debugging time.
2) Power on the computer, run NcStudio software, and then switch to ―DIAG‖ IOPort‖ window,
displaying input and output signals (in dual Z axes software, switch to ―IOPort‖). Solid dots indicate
input signals, while hollow dots output signals; dots in red indicate the signals are invalid at the time
(with no input or output), while dots in green indicate valid at the time. The ―IOPort‖ window is as
shown in Fig. 4-2. (It is for reference only. Ports displayed in the ―IOPort‖ window vary with software
version and hardware. The actual situation is in line with shipment).

3) Alter the input port polarity of the software in terms of the home switches and E-STOP button used:
the polarity of NO input ports is N, while that of NC input ports is P. The way to alter the polarity is as
follows:
