Zero-Crossing Detection

Technical Summary, Rev. 5

Freescale Semiconductor

2.16 Quadrature Encoder/Hall-Effect Interface

The 56F803EVM board contains a Quadrature Encoder/Hall-Effect interface connected to the
device’s Quad Encoder input port. The circuit is designed to 3.0V to +5.0V encoder or
Hall-Effect sensor inputs. Input noise filtering is supplied on the input path for the Quadrature
Encoder/Hall-Effect interface, along with additional noise rejection circuitry inside the
controller.

Figure 2-13

shows the encoder interface.

2.17 Zero-Crossing Detection

An attached UNI-3 motor drive board contains logic that can send out pulses when the phase
voltage of an attached 3-phase motor drops to zero. The motor drive board circuits generate a 0 to
+3.3V DC pulse via voltage comparators. The resulting pulse signals are sent to a set of jumper
blocks shared with the Encoder/Hall-Effect interface. The jumper blocks allow the selection of
Zero-Crossing signals or Quadrature Encoder/Hall-Effect signals. When in operation, the
controller will only monitor one set of signals, either the Encoder/Hall-Effect or the
Zero-Crossing.

Figure 2-13

shows the Zero-Crossing and Encoder/Hall circuits.
