Pin 3
To generate the index output, one pole of the main magnetization must be reduced so that
a difference of at least 30% is assured at the Hall amp. input.
These waveforms are shown to indicate the principles of operation, and are not actual
measured waveforms.
Burst adjustment is started by the fall of the index detector output 3, and then, it ends by
the third of fall of FG amp. output.
Incorrect pulses may be output immediately after (i.e., within about 200ms of) start-up.
If the reduction in the magnetization is inadequate, the index signal may not be generated.
Also note that excessive modulation of the Hall amp. input can cause incorrect pulses to be
generated.
