Accurate motor feedback with TCPWM_QuadDec_PDL

Precision Position Tracking: TCPWM_QuadDec_PDL Component for Gray Code-Based Counting and Direction Detection in Motor Feedback Systems.

Count digital signal transitions with TCPWM_QuadDec_PDL

The TCPWM_QuadDec_PDL Component gives you the ability to count transitions on a pair of digital signals. The signals are typically provided by a speed/position feedback system mounted on a motor or trackball.

Gray code signals for precise position detection

The signals, typically called phiA and phiB, are positioned 90 degrees out of phase, which results in a Gray code output. A Gray code is a sequence where only one bit changes on each count. This is essential to avoid glitches. It also allows detection of direction and relative position. A third optional signal, named Index, is used as a reference to establish an absolute position once per rotation.

Quadrature Decoder (TCPWM_QuadDec_PDL) features
  • 16- or 32-bit Counter
  • Counter Resolution of x1, x2, and x4 the frequency of phiA and phiB inputs
  • Index Input to determine absolute position
  • Peripheral Driver Library (PDL) Component (PDL Application Programming Interface (API) only)
