Parameter
establish the machine coordinate system. Machine reference point can be coincident with the
machine origin (in the default system setting), or not.
When home switch works normally, if spindle moves away from home switch direction in the
process of returning to the machine origin, the value of ―X/Y/Z/A direction in backing to reference
point‖ (coarse positioning direction) should be modified, please refer to question No. 2 in chapter
3.3.3 when the moving direction of machine is incorrect during backing to the machine origin. If the
speed of returning to the machine origin is quite low, users can adjust the value of ―X/Y/Z/A speed in
backing to reference point‖ (coarse positioning speed) properly. ―Retract Distance‖ refers to a
certain moving distance away from origin to leave the signal sensitive zone of home switch after
backing to machine origin ends.

Parameter
X axis screw pitch
Y axis screw pitch
Z axis screw pitch
A axis screw pitch
Related to specific machine tool, screw pitch of ―X/Y/Z/A‖ should be set after being measured in
actual operation.

FAQ & Troubleshooting
1) REF. point signal cannot be detected in the process of returning to machine origin.
It is generally caused by home switch. The debugging & adjusting steps are shown in Fig. 3-9.

Questions and answers
Y axis not coming to home
The information provided does not explicitly mention reasons why the Y-axis might not be homing on the WEIHONG NK280. However, based on general CNC controller behavior, possible reasons could include:
1. Encoder Type: If using an absolute encoder, homing may not be required. If using an incremental encoder, ensure the homing procedure is correctly executed.
2. Wiring Issues: Check connections between the NK280 controller and the Y-axis motor or encoder.
3. Limit Switch Issues: Inspect the limit switches for the Y-axis to ensure they are functioning properly.
4. Configuration Settings: Verify that homing parameters for the Y-axis are correctly set in the system configuration.
5. Software Issues: Ensure the NK280 software is properly configured and updated.
6. Mechanical Obstructions: Check for physical obstructions preventing Y-axis movement.
If the issue persists, reviewing the system configuration and error messages in the software may provide further insights.
