Compatible Replacement & Equivalent Models
When the original BM4422-ST1-01242-0309 is unavailable or end-of-life, the following models may serve as functional replacements or equivalents. Always verify electrical and mechanical compatibility before substitution.
- BAUMULLER BM4422-ST1-01242-0310 — Revised firmware variant; pin-compatible in most BM44 installations
- BAUMULLER BM4424-ST1-01242-0309 — Higher current rating variant within the same BM44 series
- BAUMULLER BM4412-ST1-01242-0309 — Lower power variant; suitable for reduced-load applications
- Siemens SINAMICS S120 (equivalent class) — Cross-brand alternative for multi-axis servo systems; requires adapter and re-parameterization
- Lenze i700 Servo Drive — Functional cross-brand equivalent for cabinet-integrated servo applications
Note: Cross-brand replacements require engineering review. Contact support@konmask.com for compatibility assessment.

Selection Guide
Use the following criteria to confirm the BM4422-ST1-01242-0309 is the correct model for your application:
- Step 1 — Verify power rating: Match the continuous and peak current output to your servo motor nameplate data
- Step 2 — Confirm bus voltage: Check DC bus voltage compatibility with your existing drive cabinet
- Step 3 — Check communication protocol: Confirm fieldbus type (PROFIBUS / CANopen / EtherCAT) matches your controller
- Step 4 — Encoder interface: Verify resolver or encoder type (incremental / absolute / EnDat / SSI)
- Step 5 — Mechanical fit: Confirm module slot dimensions and mounting rail compatibility
- Step 6 — Firmware version: For direct replacement, match firmware revision to avoid parameter migration issues
