Fault Messages
Fault Name/Description Corrective Actions
1. If P 10.05 = 1 or 2 (warn and AC drive
stop), Encoder feedback loss would be
recorded.
2. If P 10.05 = 0 (warn and continue
operation), Encoder feedback loss
would not be recorded.
1. Verify that the encoder board has power
2. Check to be sure it is not mis-wired
3. Check for incorrect voltage or encoder set-up
4. Check both the mechanical and electrical integrity of the
encoder.
Encoder A/B phase signal is in error when
the control mode is from the encoder
1.Verify power to the encoder feedback card
2. Verify encoder and feedback card wiring
3. Check encoder feedback card dip switch settings and encoder
voltage requirements
