What Cancellation means for you

You can no longer order it as a normal product, and nothing new should be designed around it. If machines depend on it, you want spare stock you can rely on and a migration plan. Both start with knowing how many you run.

How ECS defines Cancellation · all four lifecycle stages

Before replacing servo or motion hardware

Motion hardware is usually tied to the motor, feedback device, gearing, tuning, safety functions and controller-side motion instructions. We would identify those dependencies before assuming a newer unit can replace the existing one.

For a production-critical axis, planned migration gives time to retune and prove motion safely; doing that work during an unplanned stoppage is where obsolescence becomes expensive.
