Compatible Replacement & Equivalent Models
The following models are commonly evaluated as direct or functional replacements for the TDM3.2-030-300-W1. Compatibility depends on your system firmware, motor pairing, and bus topology.
| Model | Brand | Current Rating | Bus Voltage | Cooling | Compatibility Notes |
|---|---|---|---|---|---|
| TDM3.2-030-300-W0 | Rexroth | 30 A | 300 V | Air (W0) | Direct electrical equivalent; different cooling method |
| TDM3.2-020-300-W1 | Rexroth | 20 A | 300 V | Water | Lower current; verify motor load requirements |
| TDM3.2-050-300-W1 | Rexroth | 50 A | 300 V | Water | Higher current; drop-in upgrade for heavier loads |
| HDS03.2-W075N | Rexroth | 75 A | 300 V | Water | Next-gen HDS series; requires firmware/parameter migration |
| DKC03.3-040-7-FW | Rexroth (EcoDrive) | 40 A | 300 V | Air | EcoDrive03 series; different parameter structure |
Important: Always confirm motor-drive pairing using Rexroth’s motor selection tool or consult your system integrator before substitution.
Why Choose the Original Model
- Proven DIAX03 platform — field-tested in thousands of CNC and robotics installations worldwide
- Water-cooled design (W1) — ideal for high-duty-cycle applications where ambient temperature management is critical
- SERCOS fiber optic interface — deterministic, noise-immune communication for multi-axis synchronization
- Wide motor compatibility — supports MKD, MHD, and MKE servo motor families via DSF/MSF feedback
- Mature ecosystem — extensive documentation, spare parts availability, and global service network
Typical Applications
- CNC machining centers (milling, turning, grinding)
- Industrial robots and gantry systems
- Injection molding machines
- Printing and packaging machinery
- Semiconductor and electronics manufacturing equipment
- Textile and winding machines
System Compatibility
The TDM3.2-030-300-W1 is designed to operate within the Rexroth DIAX03 drive system and is compatible with:
- Controllers: Rexroth DIAX03 CNC, Indramat TDM/KDS controllers, Siemens SINUMERIK (via SERCOS)
- Motors: Rexroth MKD, MHD, MKE series AC servo motors
- Power Supply Units: Rexroth TVD, TVM, KDV regenerative power supplies (300 V DC bus)
- Feedback Systems: DSF (Digital Servo Feedback), MSF (Motor Sensor Feedback), resolver
- Bus Topology: SERCOS I fiber optic ring (2 Mbps / 4 Mbps / 8 Mbps)
Selection Guide
Use the following criteria to confirm the TDM3.2-030-300-W1 is the right choice — or to identify the correct alternative:
- Step 1 — Verify current rating: Confirm your motor’s continuous and peak current requirements. The TDM3.2-030-300-W1 provides 30 A continuous. If your motor requires more, consider the TDM3.2-050-300-W1.
- Step 2 — Confirm bus voltage: This unit operates on a 300 V DC bus. Ensure your power supply unit (TVD/TVM/KDV) matches.
- Step 3 — Cooling infrastructure: The W1 suffix requires a water cooling circuit. If water cooling is unavailable, select the W0 (air-cooled) variant.
- Step 4 — Feedback type: Confirm your motor uses DSF or MSF feedback. Resolver-only motors may require a different firmware module.
- Step 5 — Firmware version: Match the drive firmware to your CNC controller version. Contact us with your controller type for compatibility confirmation.

Replacement & Compatibility FAQ
Q: Can I replace TDM3.2-030-300-W1 with TDM3.2-030-300-W0?
A: Yes, electrically they are equivalent. The only difference is cooling method (W1 = water, W0 = air). Ensure your cabinet has adequate airflow if switching to W0.
Q: Is the TDM3.2-030-300-W1 compatible with Siemens controllers?
A: Yes, via SERCOS interface. Siemens SINUMERIK 840D and similar controllers support SERCOS drives. Parameter mapping may be required.
Q: Can I use a newer HDS or HMS drive as a replacement?
A: Functionally possible, but requires parameter migration, new motor feedback cables, and potentially updated CNC software. Consult your system integrator.
Q: Do you provide a test report or inspection certificate?
A: Yes, available upon request for all units. Please specify at time of order.
Q: What is the lead time for out-of-stock units?
A: Typically 2–4 weeks for sourcing from our global supplier network. Contact us for urgent requirements.
