3. Manual operation
3.1 Returning to reference point manually
The engraving 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, and the servo home is enabled as home signal
after sensing and then the sensing stops.
You can set the “Home mode” in [Parameter] [General parameter], and move to comprehensive home
mode (36# parameter) EOB to select. 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 follow:
(1) Each axis returns to reference point separately
