The DCS Joint Speed Check caught the named axis exceeding its configured safe joint speed.

What it means

The DCS Joint Speed Check caught the named axis exceeding its configured safe joint speed.

Common causes

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

  1. Programmed motion or override driving the axis past its DCS speed limit.

How to fix it

  1. Decrease the joint speed (program or override).
  2. As with all DCS limit hits: recurring alarms are a program/configuration disagreement to resolve deliberately.
