Internal fault – critical
SEW Eurodrive · MOVIDRIVE system
Was bedeutet F14.22 ?
Encoder 2 is signaling a critical internal fault, meaning the encoder itself has detected a severe malfunction. This prevents the drive from receiving reliable position feedback and could lead to unsafe or uncontrolled operation.
Häufige Ursachen
- Catastrophic hardware failure within Encoder 2, such as a damaged ASIC or optical sensor array.
- Complete loss of internal power regulation within Encoder 2, rendering the encoder inoperable and signaling a critical fault.
- Severe mechanical damage to Encoder 2 (e.g., bearing failure, shaft misalignment) causing internal sensor disruption.
- Persistent over-temperature condition within Encoder 2 exceeding its operational limits (e.g., >85°C) due to ambient conditions or internal failure.
Reparaturschritte & Checkliste
Klicken Sie auf Schritte, um Ihren Fortschritt zu verfolgen.
- 1
Verify the supply voltage to Encoder 2 at the encoder terminals (e.g., +10VDC or +24VDC) is within the specified tolerance.
- 2
Check the encoder housing for signs of physical damage, overheating (discoloration), or excessive vibration during operation.
- 3
Disconnect Encoder 2 and measure the resistance across its internal power supply pins (e.g., +V to 0V) to detect a short circuit.
- 4
Log any associated drive alarms (e.g., overcurrent or motor overload) that might indicate a secondary issue stressing the encoder.
- 5
As this is a critical internal fault, replace Encoder 2 with an identical, known-good unit for immediate troubleshooting.
