5.1.3. Installation Detection of Control Card
1) Join the terminal board to port JP1 on the control card with a DB37M/F cable, to DB50 interface on
the control card with a HD50F-CN50 cable, provide 24V power supply for the terminal board, and
power on the machine signal system (proximity switch, etc).
2) Examine the input signal LEDs of the terminal board: for example, if the origin switch connected is
normally closed, at this time, two LEDs of X0 and Y0 are on; trigger the origin 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 origin signals have been
sent to the terminal board. If the origin switch connected is normally open, LEDs should be usually
out, and by artificially touching the switch, LEDs should become light, which shows the origin
signals have been sent to the terminal board. The same method can be taken to test other input
ports to ensure the correctness of the wiring between the terminal board and the machine tool,
greatly shortening the debugging time.
5.2. Description of Ports Wiring
5.2.1. Ports Diagnosis of Software
1) Power on the computer, run NcEditor software, and then open
―IOPorts‖ window displaying many
input and output signals by [Ports Setting] under [Mach] menu. Solid dots represent input signals,
while hollow dots represent output signals.
2) Dots in red indicate the signals are invalid at the time (with no input or output), while dots in green
indicate the signals are valid at the time. The
―IOPorts‖ window is as shown in Fig. 5-1. (It is for
reference
only. Ports displayed in ―IOPorts‖ window will vary with different software versions and
hardware board card types. The actual situation is in line with shipment).
