A-B Phase Mode
[A-B Phase Mode] is a channel related to the encoder resolution. If the encoder supports two channels, a connection is made to the A-B phase, but if the encoder only supports one channel, the connection is made to the A phase.
There are four options in the A-B Phase Settings.
[QEP], [Count(A)-Direction(B)]: options that use two channels
[Up Count(A)], [Down Count(A)]: options that use one channel
A-B상 모드 | 설명 | |
|---|---|---|
| 1 | QEP | Quadrature Encoder Pulse Mode. This combines the counts of channels A and B to expand the resolution by four times. For example, if A and B phases have 500 counts each, the overall resolution will be 2000 = 500 4 counts. |
| 2 | Count(A)-Direction(B) | A phase is an option for counts, and B phase is an option determining the direction. Depending on the high/low status of the B phase, the count of the A phase is adjusted up or down. |
| 3 | Up Count(A) | This uses the A phase signal as an up count. |
| 4 | Down Count(A) | This uses the A phase signal as a down count. |
The [A Phase Polarity] and [B Phase Polarity] settings determine whether to use each phase as is or in reverse. Reversing each phase can change the up and down counts, so if changing the direction is the objective, using [Inverse Mode] allows more intuitive settings.
