3.6 Set the Workbench Stroke
This operation is used to set the upper limit and lower limit of the workbench, so as
to ensure the machine tool moves within a safe range.
If it is your first time to set the workbench stroke, confirm the actual size of the
machine tool before setting.
To set the workbench stroke, do the following:
1. To enable soft limit protection function, modify value of parameter Enable Soft
Limit Protection of each axis to YES.
2. According to the actual size of the machine tool, modify values of parameters
Soft Limit Lower Limit and Soft Limit Upper Limit of each axis.
For details of these parameters, see Basic Parameters.
3.7 Compensate Lead Screw Errors
This operation is used to compensate the following errors when the expected
precision is not reached due to errors in the machine tool itself, so as to improve
machining precision:
• Screw pitch errors: caused by screw defect and long-term wear, etc.
• Backlash errors: caused by a sudden violent backward movement of the
spindle.
Before compensating lead screw errors, modify the value of parameter Lead Screw
Compensation Mode and W-axis Lead Screw Compensation Mode and select a
lead screw compensation type:
• If high precision is required, modify it to 1. The system only compensates
backlash errors.
See Compensate Backlash Errors for details.
• If higher precision is required, modify it to 2. The system compensates both of
these errors, namely comprehensive errors.
See Compensate Comprehensive Errors for details.
3.7.1 Compensate Backlash Errors
To compensate backlash errors, modify value of parameter Backlash of each axis
according to the actual situation.
Restart the software to make the setting effective.
