P.039 Encoder Loss Enable
This parameter
enables the encoder
loss detection
diagnostic.
This diagnostic is
available for flux
vector control (FVC)
only.
Parameter Range: OFF = Disable encoder loss diagnostic
ON = Enable encoder loss diagnostic
Default Setting: OFF
Parameter Type: Tunable
Refer also to parameters: N/A
The encoder loss detection diagnostic is functional only when the drive is operating
as a speed regulator (not as a torque regulator).
When the diagnostic is enabled and feedback from the encoder is not detected, a
drive fault will be logged (EL will be displayed).
If the encoder fails, loss will be detected down to 1 RPM. If only one of the
quadrature feedback wires is disconnected, loss may not be detected below 15
RPM.
