3. Manual operation
3.1 Returning to reference point manually
CNC machine tool has specific mechanical position, which is called as reference point and for tool exchange and
coordinates setting. Generally, when the power supply is connected, the tool should be moved to the reference
point. This operation is also called as home operation, which will make the CNC system confirm the origin of
machine tool.
The home operation includes program and mechanical mode:
For program home, the action completes when the coordinates of machine tool are 0, and won’t check whether
origin switch is in position;
For mechanical home, the external home sensor switch is used to locate the origin of the machine tool; two
checking modes are available:
With the external sensor switch, the home operation completes when the sensing is successfully repeatedly.
The external sensor switch is used as deceleration switch, the servo home is enabled as home signal after sensing
and then the sensing stops. You can set the “Home mode” in [Parameter][Comprehensive Parameter], in which 0
(default) indicates program and 1 indicates mechanical. You can also press [SBK] key in home mode to switch
among “Mechanical – Program – Mechanical…” quickly. This method doesn’t conflict with parameter setting.
You can select accordingly. To use servo home as the home signal, you need to set “Axis phase Z home enable”
to “1” in [Parameter] [Axis Configuration] in mechanical home mode, and the setting will take effect in next
home checking.
Several methods are available for tool returning to reference point and the steps are as follows:
3.2 Each axis returns to reference point separately
Press the mode switch key [Home] to select home operation;
Press the composite key [X-], [Y-], [Z-], [A-] in the numeric section to return the corresponding axis to
reference point.
3.3 Each axis returns to reference point simultaneously
Press the mode switch key [Home] to select home operation;
Press the [Start] key to allow Z axis to return to reference point, and then other axes return to reference
point simultaneously. The automatic home sequence can be configured in the parameters.
3.4 Reset machine tool position
Press the mode switch key [Home] to select home operation;
