Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the CDB34.014.W2.4.BR.SH.OL.HF. Always verify electrical and mechanical compatibility before substitution.
- LUST LTI CDB34.014.W2.4.BR.OL.HF – Same series, without STO safety function; suitable for non-safety-rated applications
- LUST LTI CDB34.020.W2.4.BR.SH.OL.HF – Uprated to 20 A; drop-in upgrade for higher-torque motors
- LUST LTI CDB32.014.W2.4.BR.SH.OL – Previous-generation CDB32 series; functionally similar, verify firmware compatibility
- Bosch Rexroth IndraDrive Cs HCS01.1E-W0013 – Cross-brand equivalent for 14 A class servo drives; requires parameter re-mapping
- Siemens SINAMICS S120 Booksize 18 A – Industry-standard alternative; different form factor and commissioning tool
- Schneider Electric Lexium 32 LXM32MD18N4 – Comparable servo drive; compatible with IEC 61800-5-2 safety standards
Note: Cross-brand replacements require full re-commissioning. Contact Konmask technical support for compatibility assessment.
Why Choose the Original Model
- Exact parameter compatibility: Retains all original drive parameters, motor maps, and tuning data — zero re-commissioning time
- Integrated safety (STO): Factory-certified Safe Torque Off meets IEC 62061 / ISO 13849 without external safety relays
- Built-in braking & harmonic filter: Reduces panel space and BOM cost versus add-on solutions
- Proven field reliability: CDB34 series has extensive installed base in packaging, printing, and machine tool industries
- OEM warranty compliance: Using the original part number preserves machine OEM warranty obligations
Typical Applications
- CNC machine tools and machining centers
- Packaging and labeling machinery
- Printing and converting equipment
- Textile and winding machines
- Robotics and multi-axis motion systems
- Semiconductor and electronics manufacturing equipment
System Compatibility
- Compatible Motors: LUST LTI synchronous servo motors (SDS / SDH series); third-party motors with SinCos or EnDat encoders
- Fieldbus Networks: CANopen DS402, PROFIBUS DP (option card required)
- PLC Integration: Siemens S7, Beckhoff TwinCAT, Mitsubishi MELSEC, Omron Sysmac via standard fieldbus
- Engineering Software: LUST LTI CDD+ commissioning software (Windows compatible)
- Power Supply: Compatible with standard 3-phase industrial power; built-in EMC filter (HF option)
Selection Guide
Use the following criteria to confirm the CDB34.014.W2.4.BR.SH.OL.HF is the correct model for your application:
- Step 1 – Current rating: Confirm motor rated current ≤ 14 A (continuous). If motor current exceeds 14 A, consider CDB34.020 or CDB34.028 variants.
- Step 2 – Supply voltage: Verify 3-phase 200–480 V AC supply is available at the panel.
- Step 3 – Safety requirements: If machine requires SIL 2 / PLd safety, confirm STO (SH option) is mandatory — this model includes it.
- Step 4 – Encoder type: Match encoder interface (SinCos / EnDat / Hiperface) to your servo motor specification.
- Step 5 – Fieldbus: Confirm CANopen or PROFIBUS is your network protocol; specify option card if needed.
- Step 6 – Braking: Built-in braking resistor (BR) is included; verify resistor power rating matches deceleration duty cycle.

Replacement & Compatibility FAQ
Q: Can I replace CDB34.014.W2.4.BR.SH.OL.HF with a CDB34.014 without the SH option?
A: Only if your machine safety design does not require STO. Removing the SH option eliminates the certified Safe Torque Off function — consult your machine safety assessment before substituting.
Q: Is the CDB34 series still in production?
A: LUST LTI (now part of the Regal Rexnord group) has transitioned some CDB34 variants to successor platforms. Konmask maintains stock of original CDB34 units for MRO and replacement needs.
Q: Can this drive run a non-LUST servo motor?
A: Yes, provided the motor uses a compatible encoder (SinCos, EnDat, or Hiperface) and the current rating is within 14 A. Motor commissioning via CDD+ software is required.
Q: What is the lead time for this part?
A: In-stock units ship within 3–5 business days. Out-of-stock units are sourced within 2–6 weeks depending on availability. Contact us for real-time stock status.
Q: Do you provide a test report or inspection certificate?
A: Yes. Inspection reports are available upon request for all units. Certificates of conformity can be provided for bulk orders.
