Common causes
Ranked by what technicians most often find, most likely first.
- Internal amplifier overheat/fault.
How to fix it
- Replace the servo amplifier with the controller de-energized and locked out, then power-cycle to clear.
- Cabinet cooling is still worth a glance. A cooked amplifier in a hot cabinet will be followed by another.
