The zero signal is only output if released by the
input pins (for instance with PZERO = 5 V, NZERO =
VREF).

Figure 12: Incremental output signals for various length of the zero signal.
Example for a resolution of 64 (SELRES = 0x0A), a zero signal position of 0° (ZPOS = 0x00,
CFGAB = 0x00) and no reversal of the rotational sense (ROT = 0x00, COS leads SIN).
