Delta AL024 fault code meaning
Delta / AL024
Series: ASDA-A2-E, ASDA-A2, ASDA-A2R, ASDA-B2
Encoder initial field error
servo drive
Meaning:
Possible causes
- Encoder initial field error
- (Field position UVW error)
- 1. Check whether the motor ground terminal is properly grounded.
- 2. Check whether the encoder signal cable and the power supply
- or separate from high-current lines to avoid
- Generation of interference sources
- 3. Check whether the position detector wiring uses
- Off-grid
- Inspect and repair
