Ferrocontrol FMR071‑12‑60‑RBK‑00 is a high‑speed AC servomotor rated at 14.7 A and 296 V with a 6000 rpm output shaft, commonly paired with DARC or DARC 2 drive controllers. Typical failure modes for this model include winding insulation breakdown (visible as increased resistance or shorted turns), bearing wear leading to excessive vibration or noise, and resolver signal loss due to cable damage or connector corrosion. For initial troubleshooting, verify the supply voltage and phase balance at the motor terminals; inspect the rotor/shaft for physical damage and confirm that the resolver leads are clean and securely connected; finally review any fault codes from the attached drive for indications of over‑temperature, over‑current, or encoder errors.[oss-gpt-20b]
