Figure 2-9 Rotary axis with rotary encoder on motor
In order to adapt the actual-value resolution to the calculation resolution, the control
calculates the quotients from the "internal increments/degree" and the "encoder
increments/degree" as follows:
Example for rotary axis with encoder on motor
Rotary axis with rotary encoder (2048 Impulse) on motor;
internal multiplication (2048)
Gear: Motor/rotary axis 5
1000 increments per degree
