Description
The Siemens 6FC5370-2AT03-0AA0 is a SINUMERIK 808D Advanced operator panel / HMI (PPU – Panel Processing Unit) used in Siemens CNC control systems.
It is a human–machine interface (HMI) + CNC control panel, not a drive or motor.
🔧 Basic Identification
| Feature | Details |
|---|---|
| Manufacturer | Siemens |
| Series | SINUMERIK 808D Advanced |
| Part Number | 6FC5370-2AT03-0AA0 |
| Type | Operator Interface / PPU (Panel Processing Unit) |
| Function | CNC control + HMI display + machine operation |
| Layout | Horizontal version (T-type PPU 161.3) |
| Application | CNC machines (lathe & milling) |
📌 Siemens official catalog lists it as:
“SINUMERIK 808D, Extended T PPU 161.3 horizontal with current software version”
⚙️ What it does
This unit is the main operator control panel of a CNC machine. It is used for:
- Machine operation (start/stop, jog, reset)
- Program input (G-code editing)
- Axis movement control
- Tool and spindle control commands
- Displaying alarms and diagnostics
- CNC system communication (with drives and PLC)
🧠 System Role in CNC Machine
In a typical Siemens CNC system:
Operator Panel (6FC5370-2AT03-0AA0)
→ sends commands to
SINUMERIK CNC controller
→ controls
servo drives + spindle drives
So it is the brain interface between operator and machine.
🏭 Applications
- CNC turning machines (lathes)
- CNC milling machines
- Small to medium CNC production machines
- Educational / industrial CNC systems using SINUMERIK 808D
