(Note) The correct output waveform of the encoder is as follows:
@
When the spindle of the machine rotates counterclockwise at approx. 500 rpm
while the bit
8
of the parameter
ORSZ
is 0:

___.
@
When the spindle of the machine rotates clockwise at approx. 500 rpm and when
the bit 8 of the parameter OSR2 is 0,
the same waveform as the above figure
occurs.
