Machining Operations
4.4. Setup of Machine Stroke
Machine stroke refers to the valid motion stroke of a machine tool. In the parameter
―MachineStrok‖, the
valid motion range of the three axes (X/Y/Z) can be set. Because this system regards the machine tool
dimensions as the reference for soft limit, their values should be consistent with the actual dimensions of
the machine tool. Otherwise, limit overrun or axis crash may occur.
If file machining range exceeds the machine tool‘s dimensions, there will be a message box prompting
machining is out of range, as shown in Fig. 4-5. You can press [OK] or [ESC] to return to the main page,
and then manually move the machine tool to release limit.

Modification to this parameter becomes valid after system reboot.
4.5. Port Polarity Adjustment
The polarities of input/output ports in the software are specified in terms of the switch type: the polarity of
a normally closed switch is
―P‖; the polarity of a normally open switch is ―N‖. The corresponding relation
between system port No. and ports on the terminal board is as shown in Table 8.
The steps to modify port polarity are as following: press
―Menu‖

press [OK] to enter the interface as shown in Fig. 4-6. At this time, you can press the
―Up‖ or ―Down‖ key
to move the cursor to the desired port, and then press the
―Shift‖ key to change its polarity. After its
polarity change, press [OK] to save the modification.
