Selection Guide
Use the following criteria to determine whether the A1A1000043202M or an equivalent model is right for your application:
- Step 1 – Identify your drive series: Confirm the SIEMENS drive model number (e.g., 6SE70xx, 6RA70xx) from the nameplate.
- Step 2 – Check revision compatibility: Match the board revision suffix (e.g., 02M) to your drive’s firmware version requirements.
- Step 3 – Verify interface type: Confirm communication interface (PROFIBUS, PROFINET, or analog) matches your control architecture.
- Step 4 – Assess power rating: Ensure the control board is rated for your drive’s power class (kW range).
- Step 5 – Confirm physical dimensions: Verify PCB form factor and connector pinout against your existing board.
