Specialized Concentrated Focused 2. Principle of System Signal The signal types of NK105G2F/G3F system can be divided into the following 4 types: binary input signal, open collector output signal, differential output signal and analog output signal. 2.1. Binary Input Signal Binary input signal is active low and supports NO and NC input signals (through modifying input port polarity in the software).
Specialized Concentrated Focused Power Requirement It is recommended to adopt DC24V/4.5A switch power for relays on the terminal board. If there are a great many DC 24V relays controlled by binary output signal, you can appropriately expand the power source capacity or add extra power (forcibly sharing ground with external power supply).
Specialized Concentrated Focused 2.2. Open Collector Output Signal The output ports on the control box are open collector output, with maximum output current 500mA. 2.3. Differential Output Signal Differential signal refers to two equivalent signals with opposite phases sent by driving end, and the voltage difference of these two signals is used for deciding whether the logical status of differential signal is ―0‖...
Specialized Concentrated Focused 3. System Page Manual operation mode is activated by default when the system is started. Default interface is machining page, on which axis, coordinate, operating state, spindle state, manual speed as well as operation mode are displayed, as shown Fig. 3-1. Besides, tips for operation will be shown on bottom part of the page. 0.000 空闲...
Specialized Concentrated Focused IDLE State Idle state is the most common state. Under this state, the machine has no motion to output, but is ready to accept any new task. ESTOP State This is an abnormal state. When there is an error in the hardware of the machine tool, the system will enter into this state and implement the predetermined protection actions, such as closing spindle motor and cooling pump.
Specialized Concentrated Focused For milling machines, the direction of machine axes is decided by both the type of machine tool and the layout of each component. The basic coordinate axes of milling machines are X-axis, Y-axis, and Z-axis: ——Z-axis is coincidental with spindle axis and the direction of the cutter moving away from workpiece is its positive direction (+Z).

Specialized Concentrated Focused One, two or several workpiece offsets can be used in one machining program. As shown in Fig. 3-4, three workpieces are installed on the worktable, so each workpiece has a workpiece origin corresponding to the G code of workpiece coordinate system. To drill a hole on each of the workpiece, with calculation depth as Z-0.14, the programming example is as follows.
Specialized Concentrated Focused hole for the third workpiece of the same batch within G56 WCS. Applicable to all WCSs, public offset is used to adjust the workpiece origin of X, Y and Z axes, without changing the offset value of G54~G59. Workpiece offset, tool offset and public offset meet the following expression: Workpiece coordinate = Machine coordinate –...
