SIEMIENS 1FK6 series three-phase servo motor

Severe motor vibration: 1. Coupling/load imbalance; 2. Poor alignment of the drive chain; 3. Loose fixing screws. 1. Rebalance the load and coupling components; 2. Calibrate the coaxiality of the drive chain; 3. Check and tighten all fasteners

Abnormal operating noise (abnormal noise): 1. Foreign objects enter the interior of the motor; 2. Bearing wear or damage; 3. Permanent magnet displacement: 1. Stop the machine for inspection and remove foreign objects; 2. Replace the bearings; 3. Contact Siemens for professional maintenance

Motor overheating (surface temperature>140 ℃) 1. Load exceeding rated torque; 2. Insufficient heat dissipation gap or surface dust; 3. Temperature sensor malfunction: 1. Reduce the load to the rated range; 2. Clean the surface dust and increase the heat dissipation gap; 3. Repair or replace the temperature sensor

Encoder signal abnormality: 1. Encoder wiring error; 2. The encoder is subject to electromagnetic interference; 3. The encoder is damaged. 1. Check the wiring diagram and rewire it; 2. Strengthen cable shielding and grounding; 3. Replace the encoder and calibrate it

（5） Equipment Disposal Standards

When the motor is scrapped, it should be classified and recycled according to national/local regulations, or returned to Siemens for disposal. It is prohibited to dispose of it at will;

Encoders, brakes, and other electronic components need to be disposed of separately as electronic waste to avoid environmental pollution;

Before disposal, it is necessary to remove the permanent magnets inside the motor (operated by professionals) to prevent strong magnetic fields from causing harm to disposal personnel or equipment.
