Short Name: CI.Encoder.ZIndexPhase

Property of DAQmx Channel

Specifies the states at which signal A and signal B must be while signal Z is high for NI-DAQmx to reset the measurement. If signal Z is never high while signal A and signal B are high, for example, you must choose a phase other than A High B High.

When signal Z transitions to high and how long it stays high varies from encoder to encoder. Refer to the documentation for the encoder to determine the timing of signal Z with respect to signal A and signal B.

A High B High (10040) Reset the measurement when signal A and signal B are high.
A High B Low (10041) Reset the measurement when signal A is high and signal B is low.
A Low B High (10042) Reset the measurement when signal A is low and signal B high.
A Low B Low (10043) Reset the measurement when signal A and signal B are low.
