Delta AL0C5 fault code meaning
Delta / AL0C5
Series: ASDA-W3
External sensor temperature exceeds the protection upper limit
servo drive
Meaning: 1.PM.022 = 1, and temperature > 100°C. 2.PM.022 = 2 or 3, and temperature > the temperature corresponding to resistance PM.024.
Possible causes
- Conditions:
- PM.022 = 1, and temperature > 100°C.
- PM.022 = 2 or 3, and temperature > the temperature corresponding to resistance PM.024. Cause:
- Continuous operation above the rated motor load.
- Poor heat dissipation conditions.
- Incorrect settings for PM.022 and PM.024.
- Temperature sensor error.
- Wiring error.
