Encoder commutation signals

￭
Encoder commutation signals (one sine/cosine period per revolution) should be
connected to FEN-11 inputs SIN_CM and COS_CM according to the figure below (if
such signals are available).
2.5 V
1 Encoder channel: SIN_CM
2 Encoder channel: COS_CM

Reference mark

The zero reference output channel (usually marked 0, N or Z) needs to be connected
in positioning applications only.
