Cause : Internal fan faulty comes when the internal fan has failed. If the internal fan in your Siemens SINAMICS G120 drive has failed, it's important to address this issue promptly to prevent overheating and potential damage to the drive components.
Here's how you can handle a failed internal fan:
-
Stop Operation: Immediately stop the operation of the drive to prevent any further damage. Continuing to use the drive without proper cooling can lead to overheating and may cause more severe issues.
-
Safety First: Ensure that all safety protocols are followed. De-energize the drive and isolate it from the power source before attempting any inspection or repair work. Use appropriate personal protective equipment.
-
Visual Inspection: Open the enclosure of the SINAMICS G120 drive and visually inspect the internal fan. Check for any visible signs of damage, blockages, or obstructions that may have caused the fan failure.
-
Check Fan Connections: Verify that the fan is securely connected to its power supply and control circuitry. Loose connections or damaged wiring could prevent the fan from operating properly.
-
Inspect Fan Blades: Check the fan blades for any signs of damage, wear, or imbalance. Damaged or worn-out fan blades may not provide adequate airflow, leading to insufficient cooling and potential overheating of the drive.
-
Replace the Fan: If the internal fan is damaged or malfunctioning, it will need to be replaced. Contact Siemens technical support or your authorized Siemens distributor to obtain a replacement fan suitable for your SINAMICS G120 drive model.
