Connecting Incremental Encoders
Incremental Encoders
Incremental encoders typically have channel A and channel B. By monitoring both
the number of pulses and the relative phase of channels A and B, you can track both
the position and direction of rotation. Some encoders have a third channel, channel
Z, which is also referred to as the index channel. A high level on channel Z causes
the counter to be reloaded with a specific value in a specific phase of a cycle.
Connecting Single-Ended Incremental Encoders
You can connect single-ended incremental encoders to the NI-9361.
