Load shaft encoder
Orientation control with an Encoder is used for positioning based on dividing 1 rotation into 4,096 steps (i.e.,
a resolution of 0.088_), 12-bit binary, or 3-digit BCD stop angle references using the load shaft (machine-tool
main shaft, etc.) Encoder, and the Encoder Orientation Card. Positioning can be performed using the motor en-
coder signal if the load shaft and motor shaft are coupled 1:1 and there is no play.
