(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 of the parameter
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.
