AP. APPLICATIONS
This chapter describes some particularities of the Servo Drive system:
- Considerations for the system start-up with Sercos interface.
- Adjustment of the motors for spindle at low rpm.
- Motor locking function, Halt.
- Monitoring the drive's internal variables.
- Set of Parameters and Gear Ratios.
- Spindle overload detection.
Important:
The features documented in this chapter need the following software versions:
8050/55 CNC versions V13.02 (mill) and V12.01 (lathe).
Drive versions V03.01 and later.
AP.1 SERCOS CONNECTION WITH THE 8050/55 CNC
Sercos is a communications standard designed especially for the machine-tool industry and
simplifies the connection between CNCs and servo drives of different manufacturers.
All the data and commands are transmitted in digital format through fiber optic lines. These
lines form a ring interconnecting all the electronic elements forming a system (CNC and servo
drives).
The Drives with Sercos interface carry special connections for the fiber optic lines with the
display and their sales reference is SI, and S0, for example, AXD1.25.SI.0, SPD2.75.S0.0
The Sercos interface reduces considerable the needed hardware and simplifies the cabling
making the system more robust since it improves its immunity to electrical noise.
See chapter IN of this manual.
