The pulse width of the enlarged output index pulse corresponds to the distance
between two input index pulses (with index divider > 1 only).

This mode of index treatment requires divider settings of the A/B impulse divider
and the index divider that ensure a clear assignment of the output index pulse to
the A/B output frequency, with no cumulating remainders. Where the signal
division does not come out even, jumps of the output index pulse position will
occur.
Example: With use of a 1000 ppr encoder we would set the A/B impulse divider to
3 and the index divider to 2. As a result the index output pulse should appear after
every 666.6….. input pulses, what physically is impossible without jumps.
*) Pulse width = 1/4 output period, even with index divider set to 1:1
**) Divider setting 1:1 will bypass the input index pulse to the output
