What the G5 HIGH INERTIA designation means in the field
The G5 HIGH INERTIA label tells you this motor has a larger rotor inertia than a standard servo. That's a deliberate choice for applications where the load inertia is high or varies — think a large rotary table or a heavy conveyor roller. The higher rotor inertia smooths out the response and keeps the gain tuning stable without needing a massive external flywheel. It's not a general-purpose replacement for a standard-inertia servo; if your original machine design called for this specific inertia match, swapping in a standard rotor will fight you on tuning and settling time.
