Detailed Description
2.3 Setpoint/actual-value system
Velocities, Setpoint/Actual-Value Systems, Closed-Loop Control (G2)
2-46 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
In order to adapt the actual-value resolution to the calculation resolution, the control
calculates the quotients from the "internal increments/mm" and the "encoder increments/mm"
as follows:

Fig. 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 pulses) on motor;
internal multiplication (2048)
Gear: Motor/rotary axis 5
1000 increments per degree
