Delta AboF fault code meaning
Delta / AboF
Series: C2000 Plus
PG card ABZ open
AC motor drive
Meaning: When using an encoder with ABZUVW signals, a AboF error is triggered if an open ABZ signal circuit is detected (only PG02U supports open-circuit detection).
Possible causes
- Encoder ABZ signal open

Series: DPD-K
PG card ABZ open protection
AC motor drive
Meaning: ABZ open protection when using PG02U (DPD-K does not have this fault code)
Possible causes
- PG card signal cable not connected or open
- PG card screws loose
- Malfunction due to interference
- Hardware fault
- 1.
- 2.
- The VP power supply on the PG card has no output or an output voltage level error
- 3.
- Encoder damaged
- Excessively long encoder wiring causes the PG card's
- VP power supply voltage drop too large
- 1.
