Which outcome occurs when a servomotor in a CNC lathe loses encoder feedback while cutting hardened steel?

💡 Explanation

Runaway axis motion ensues because the **closed-loop control** fails without positional feedback, therefore the motor accelerates unchecked attempting to reach a phantom target, rather than maintaining programmed trajectory. Decreased depth, spindle speed changes, or coolant pressure stability are unrelated outcomes.
