SRVO-115: Limit error

The taught path would carry the named axis outside its axis limit - the motion plan itself exits the legal envelope, so the controller refuses it.

What it means

The taught path would carry the named axis outside its axis limit - the motion plan itself exits the legal envelope, so the controller refuses it.

Common causes

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

  1. Taught points or path geometry requiring travel beyond the axis software limit.

How to fix it

  1. Re-teach the program points inside the working envelope.
  2. Or use JOINT motion type, which can resolve paths that Cartesian interpolation forces through the limit.
