Values
Description
"No Fault" (1)
No fault reported by the primary
encoder.
"Config" (2)
The encoder's configuration is invalid.
"Max Speed" (3)
The encoder speed has exceeded the
configured maximum speed.
"Max Accel" (4)
The encoder acceleration has exceeded
the configured maximum acceleration.
"Sin2+Cos2" (5)
The encoder has failed the vector length
or aspect ratio checks.
"Quadrature" (6)
The encoder has exceeded the maximum
number of quadrature signal errors.
"Discrepancy" (7)
The associated dual channel feedback
instance has reported a discrepancy.
"Partner" (8)
The associated dual channel feedback
instance has detected a fault in the other
encoder.
"Voltage" (9)

of the configured range.
"SignalNoise" (10)
The encoder signals have noise that is
preventing operation.
"Signal Lost" (11)
The encoder signals are not present.
"Data Lost" (12)
Stopped receiving data from a Digital
Encoder.
"Device Fail" (13)
