SRVO-402: DCS Cart. pos. limit
The DCS Cartesian Position Check caught the robot (or a user-defined model on it) outside a configured safe zone.
What it means
The DCS Cartesian Position Check caught the robot (or a user-defined model on it) outside a configured safe zone. This is DCS doing its job - the software fence held. The message decodes which zone (check number and comment), which group, and which model (0 = the robot itself). Recovery has its own two-key ritual.
Common causes
Ranked by what technicians most often find, most likely first.
- The robot genuinely moved to the edge of or outside the zone - program change, new tooling changing the model envelope, or a jog too far.
- Zone configured tighter than the real process needs.
How to fix it
- If the robot is actually out of the safe zone: hold SHIFT and press RESET, then jog the robot back into the zone - the SHIFT+RESET combination is what permits motion while the zone check is violated.
- If production keeps kissing the boundary, the fix is a program/zone review - re-teach the path or, deliberately and through the DCS apply process, adjust the zone. Zones exist because something (person, fixture, wall) is on the other side; widen them only with the risk assessment in hand.
