Figure 5-24 Increcremental Interface startup pulses frequency
IIF Index
The IFC pin -or IIF Index- generates one pulse at zero crossing. This output can be used as check or as
comparison with the Phase A/Phase B outputs. The IIF Index pulse will be generated when the internal
Incremental Interface Counter steps over 0°. The IIF Index pulse width (t
0°
) duration is specified in Table 5-13.
