Quadrature Encoder Count Error
With quadrature encoders, the Power Brick Controller has the capability of trapping encoder count (loss)
errors. This is described in detail in the
Encoder Count Error
section of this manual.
Quadrature Encoder Loss Detection
Warning
Loss of the feedback sensor signal is potentially a very dangerous
condition in closed-loop control, because the servo loop no longer has
any idea what the true physical position of the motor is – usually it
thinks it is “stuck” – and it can react wildly, often causing a runaway
condition.
With quadrature encoders, the Power Brick Controller has the capability of detecting the loss of an encoder
signal. This is described in detail in the
Encoder Loss Detection
section of this manual.
Note
Note the distinction between the encoder count error, which reports
loss of counts due to bad transitions of the quadrature signals, and
encoder loss, which indicates that one or more quadrature signals are
missing.
