General encoder phasing principle
When the encoder is connected correctly, running the drive in the Forward (positive
speed reference) direction should produce a positive encoder feedback.
On incremental encoders, the two output channels, usually marked 1 and 2 or A and
B, are 90° (electrical) apart from each other. When rotated clockwise, most encoders
have channel 1 leading channel 2 as illustrated below. Determine the leading channel
by referring to the encoder documentation or by measuring with an oscilloscope.
