Code SVGN-168: Push depth %s[mm] exceeds strokelimit
Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Push depth %s[mm] exceeds strokelimit alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Cause: The pushing depth specified in the pressure schedule or the minimum pushing depth, exceed the stroke limit. The contact speed might be slightly lower than specified as a result of this alarm. Remedy: Update one or more of the parameters used to specify pushing depth: $sgsch#[].$push_depth and $sggun.$setup.$push_margin. If these parameters cannot be reduced, then increase the stroke limit, if possible. Note that this is only a warning.
