What to check · Que vérifier

• Inspect the Drive unit configuration error, its wiring and connections first.
• Match this code against your robot's event-log timeline before swapping parts.
• Follow the French field checks below — they are the tested sequence for this fault.
• probable : Too many joints are using same measurement excitation and all are using same drive unit.
• Move the joint or another joint with same node excitation to the other excitation (EXC1 - EXC2), by reroute the joint measurement node connection both in hardware and in configuration.
