SRVO-026: Motor speed limit

A warning, not a stop: the commanded motion asked for more than the motor's maximum rated speed, so the controller clamped it at the limit.

What it means

A warning, not a stop: the commanded motion asked for more than the motor's maximum rated speed, so the controller clamped it at the limit. The robot keeps running - just not as fast as the program asked.

Common causes

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

  1. Programmed speed (usually a linear move forcing a joint to its limit) exceeding the motor's rated maximum for that axis.

How to fix it

  1. Nothing is broken - the clamp protects the motor automatically.
  2. To make the warning go away, reduce the taught speed on the offending motion.
  3. Repeated clamping on the same move is a hint the path geometry is forcing one joint to do too much work - consider re-posing.
