Selection Guide
Use the following criteria to select the correct feedback module for your application:
- Step 1 — Identify encoder type: TTL incremental, sin/cos, or absolute (EnDat/SSI)
- Step 2 — Check axis count: Single-axis (1BA) vs. dual-axis configurations
- Step 3 — Verify revision suffix: -0BA1 suffix indicates specific hardware revision; confirm with drive documentation
- Step 4 — Match CNC controller: Ensure compatibility with your SINUMERIK version
- Step 5 — Confirm power supply: Module is bus-powered; no external 24 V required in standard configurations

Replacement & Compatibility FAQ
Q: Can I use 6SN1145-1BA02-0BA1 as a direct replacement for 6SN1145-1BA01-0BA1?
A: In most cases yes, as the -1BA02 is a later revision with backward compatibility. However, always verify with your drive commissioning documentation or contact us.
Q: Is this module compatible with SINUMERIK 840Di?
A: The 840Di uses a different drive interface (PROFIBUS-based). This module is designed for the analog/digital SIMODRIVE 611 platform. Please consult us for 840Di-compatible alternatives.
Q: Do you supply refurbished units?
A: We supply both new and professionally refurbished units. Refurbished units are clearly labeled and carry a 6-month warranty.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–4 week lead time. Contact us for real-time availability.
Q: Can Konmask provide a cross-reference for other brands?
A: Yes. We maintain cross-reference databases for major drive brands. Contact our team with your current part number for a verified equivalent recommendation.
