SRVO-101: Robot overtravel (Group)

Group-level version of SRVO-005: an axis in the named group tripped its hardware limit switch.

What it means

Group-level version of SRVO-005: an axis in the named group tripped its hardware limit switch. Same shipping-state caveat - new robots arrive deliberately set in overtravel for transit.

Common causes

Ranked by what technicians most often find, most likely first.

  1. Same as SRVO-005: shipping overtravel state, an axis driven into its hardware limit, or a faulty limit switch/wiring.

How to fix it

  1. Work the SRVO-005 remedy: SHIFT+RESET to clear, keep SHIFT held and jog back into range, use the OT release screen on uncalibrated robots, and suspect the switch if nothing is near a limit.
