The Advantages of New Siemens 808D Advance System are as below:-

The benefits are as per below.

1. It is close loop system so positioning accuracy of axis is far better.

2. It has Auto servo tuning (AST) facility so that load can be tuned with servo motor for better performance with torque.

3. It has Direct servo control (DSC) by Drive Bus communication so that drives can perform better with controller commands.

4. It has friction compensation facility.

5. Servo motors available up to 40Nm whereas in 808D it was only 4,7,10Nm only.(eg. for Z-axis we used 15Nm

6. Absolute encoder available with Servo motor so that referencing is not required (like 828D)

7. It has Ethernet communication port so that PLC and Data Upload/Download is much faster.

8. It has Ethernet Interface so that it can be monitored remotely (like 828D) for

a. Transfer of Part program, user cycles, Machine data, R-parameter, PLC data, HMI data etc..

b. PLC Logic can be monitored

c. PLC upload/download

d. Part program send/receive

e. Execute part program

f. Screen shots can be taken.
