- Parameter Storage: Holds up to 10 complete parameter sets [citation:2]
- Protection Class: IP20 [citation:2]
- Power Supply: Powered directly from the inverter
- Communication Interface: RS485, RS232 [citation:2]
- Control Functions: Start, Stop, Reverse, Jog [citation:2]

- Storage Temperature: -10°C to 55°C [citation:2]
- Humidity: Max 95% at 25°C, non-condensing [citation:2]
- Weight: 0.45 kg [citation:2]
- Certifications: UL, CE, C-Tick [citation:2]

Supported Functions:
- Full parameter programming and editing
- Upload/download parameter sets to/from drive
- Store up to 10 parameter sets in internal memory [citation:2]
- Fault and warning code display with descriptions [citation:2]
- Real-time monitoring of actual values
- Local control (start, stop, direction, jog)
- Parameter comparison between stored sets and drive

Typical Applications:
- Multi-drive systems requiring parameter cloning
- Applications with frequent parameter changes (different product recipes)
- Remote commissioning and troubleshooting
- OEM environments where drives need identical programming
- Maintenance spares for quick drive replacement

Key Features:
- Backlit LCD provides clear visibility in low-light conditions [citation:2]
- Parameter set storage eliminates re-programming time (10 complete sets) [citation:2]
- Fault codes displayed with plain-text descriptions for easy diagnosis [citation:2]
- RS232 interface for PC connection (using optional adapter)
- RS485 interface for direct connection to drive communication networks
- Can be used as a portable programmer across multiple drives

BOP vs AOP Comparison:
| Feature | BOP (0BP00-0AA1) | AOP (0AP00-0AA1) |
|---------|-------------------|-------------------|
| Display | 5-digit LED | Multi-line LCD with backlight |
| Parameter Storage | No | Yes (10 parameter sets) |
| Fault Description | Code only | Code + description |
| Local Control | Basic | Start/Stop/Reverse/Jog |
| PC Connectivity | No | Yes (RS232) |

Important Notes:
- MICROMASTER 430 drives are NOT compatible with this AOP (use BOP or other options)
- This product has been discontinued by Siemens (PM410). Available while stock lasts.
- For Chinese language interface, order the Asian version 6SE6400-0AP00-0AB0 [citation:8]

FAQ:

Q1: What is the main advantage of AOP over BOP?
A: The AOP offers a multi-line backlit LCD for better visibility, can store up to 10 complete parameter sets for quick cloning across multiple drives, and provides plain-text fault descriptions rather than just codes [citation:2].

Q2: Can I use this AOP with MM430 drives?
A: No. The 6SE6400-0AP00-0AA1 is only compatible with MICROMASTER 420 and 440 series. For MM430 drives, use the Basic Operator Panel (BOP) instead [citation:2].

Q3: How do I upload parameters from a drive to the AOP?
A: Connect the AOP to the drive, power up, navigate to the parameter upload function in the AOP menu, and select "Upload" to copy drive parameters into AOP memory.

Q4: Can I download saved parameters to a different drive?
A: Yes. The AOP can store parameters from one drive and download them to other identical drives, making it excellent for cloning configurations across multiple VFDs.

Q5: How do I connect the AOP to a PC?
A: The AOP has an RS232 interface. A PC connection requires the Siemens PC connection kit (order separately) with appropriate software.
