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.
