In V8 version: press Ctrl, Alt and Shift simultaneously, while right clicking the signal to be modified
its polarity, a menu to appear, and then choose ―Toggle Polarity‖. After changing the polarity of all desired
ports, close and restart NcStudio, polarity modification to become valid instantly.
In V9 and V10 versions: directly click the manipulation button [ConvtPol] under [IOPort] screen of
[DIAG] function section. After changing the polarity of all desired ports, close and restart NcStudio,
polarity modification to become valid instantly.
4) Electrify the electrical box. At this time, the dots in front of such input signals as REF. point signals of
the three axes, E-STOP signal, cycle start/stop signals and tool sensor signal should be in red,
indicating all these signals are invalid. Otherwise, it is necessary to check the correctness of
electrical circuitry and signals polarity. If electrical circuitry is correct, alter the corresponding signal
polarity to ensure the dots in front of the above-mentioned signals red.
5) Test whether the inputs and outputs on the controller work normally. For an input, the method is as
following: short circuit an input and COM on the controller: if the corresponding LED on the controller
turns on, but the corresponding input in the software does not have the signal, you need to check
the connection of the cable DB9M/F between the communication card (NC65A/65B host) and the
controller. If the LED does not turn on, you need to check whether the controller meets a fault (like
power supply issue). For an output, the method is as following: click the ―TestOn‖ and ―TestOff‖
buttons in the software, and observe whether the corresponding LED on the controller turns on or off
accordingly. If so, the output works normally; if not, check the connection of the cable DB9M/F
between the communication card (NC65A/65B host) and the controller.
6) Set inverter parameters to make the inverter work under 0~10V analog voltage control mode.
Spindle ON/OFF adopts forward rotation terminal control mode. Press down the [Spindle Start]
button in the software, and observe in the IOPort window whether the color of signal dot in front of
―Spindle‖ turns green, on the controller whether the green output indicator LED beside the
corresponding relay becomes brightening, and whether the spindle starts to rotate. If the spindle
does not rotate, please examine the connection of the inverter. Adjust the spindle speed in the
software and the actual spindle speed should be changed correspondingly; otherwise, examine the
connection and the parameters setting of the inverter. If the spindle rotates in a wrong direction, you
can change the settings of the relative inverter parameters, or change the connection between the
spindle and inverter: usually, there are three wires connected with the spindle. Exchanging any two
of them will alter the spindle rotation direction.
7) Set the relative parameters of servo driver. Refer to Section 5.4 for the setting of driver parameters.
8) Set pulse equivalent in the ―manufacturer parameters‖ of Ncstudio. The password of manufacturer
parameters is ―ncstudio‖. The smaller the pulse equivalent is, the higher the resolution will be. The
value of pulse equivalent will affect the maximum feed speed. Generally speaking, regarding the
pulse equivalent of a mold machine, 0.001mm/p (the corresponding maximum feed rate is
9600mm/min) or 0.0005mm/p (the corresponding maximum feed rate is 4800mm/min) can be taken
into consideration; for users who are not very critical of the accuracy, the pulse equivalent can be set
a litter larger, such as 0.002mm/p (the corresponding maximum feed rate is 19200mm/min) or
