A KUKA PRC turntable that turns red near position 3220 may be showing either a simulation defect or an axis-limit condition. The available evidence confirms that the simulation issue had been corrected internally, but the corrected build had not yet been released at the time of the report. It also confirms that KUKA turntables have configurable axis limits.
Separate the Simulation Defect from an Axis Limit
Do not assume that position 3220 is the mechanical rotation limit. The position unit, permitted range, affected software version, and exact meaning of the red display are not identified. Because the reported software defect and a genuine axis limit can produce similar symptoms, diagnose them separately.
| Possible cause | Evidence | Decision |
|---|---|---|
| Simulation defect | A correction had been completed, but the updated build was not yet uploaded. | Determine whether the installed build includes that correction. |
| Configured axis limit | KUKA turntables have an axis limit. | Inspect the turntable-axis limit configuration. |
| Physical restriction | Tilting axes are physically limited. | Do not enable infinite rotation on a tilting axis. |
Check the Installed KUKA PRC Build
The affected and corrected version identifiers are not provided, so a version-number comparison is not possible from the evidence. Confirm through the official KUKA PRC release information or support channel whether the installed build contains the reported turntable-simulation correction. Retest the same motion after updating to a build confirmed to include the fix.
Review the Turntable Axis Limit
If the behavior remains after confirming the software correction, inspect the configured limit for the turntable axis. A KUKA turntable can be configured for infinite rotation in the same general manner described for axis A6, but the evidence does not identify the command, parameter, or user-interface location.
- Identify whether the simulated external axis is a continuously rotating turntable or a tilting axis.
- For a continuously rotating turntable, review its axis-limit configuration and enable infinite rotation only if the modeled mechanism permits it.
- For a tilting axis, retain finite limits because its motion is physically restricted.
Verify the Correction
Run the original simulation path through position 3220 and observe the axis state. The correction is successful only if the continuously rotating turntable passes that position without turning red and without violating the modeled mechanism's permitted motion. If it still turns red, record the installed build, axis type, configured limits, commanded position, and position units before escalating through an official support channel.
FAQ
Why does my KUKA PRC turntable turn red at position 3220?
The evidence supports two possibilities: a simulation defect or a configured turntable-axis limit. Position 3220 is not confirmed as a mechanical limit, and its units are unspecified.
Can a KUKA turntable use infinite rotation?
Yes, the evidence states that a KUKA turntable can be set for infinite rotation, similarly to A6. Apply that setting only when the modeled mechanism supports continuous rotation.
Should I enable infinite rotation for a KUKA tilting axis?
No. Keep a tilting axis finitely limited because the evidence identifies it as physically restricted.
