Remarks 1.
The current value of the actual wave is approximated to the value shown on the page 5.
2.
The C1, C2, D1, and D2 pins of
β
channel correspond to the A1, A2, B1, and B2 pins of
α
channel.
3.
The CW mode is set if the D6 bit of the fifth and ninth bytes of the data is “0”.
4.
The CCW mode is set if the D6 bit of the fifth and ninth bytes of the data is “1”.
Note
CW mode : Position No is incremented.
CCW mode: Position No is decremented
