Product Introduction
INDRAMAT TVD1.3-15-03 Overview
The INDRAMAT TVD1.3-15-03 is a TVD series power supply module designed for modular Indramat AC servo drive systems. It converts three-phase AC input power into a regulated 320VDC intermediate circuit used by connected drive modules. The unit provides 15kW continuous DC bus power for applications requiring coordinated servo drive operation.
The INDRAMAT TVD1.3-15-03 is commonly installed in CNC machines, production equipment, and multi-axis motion systems. Its value is in maintaining a stable DC bus for multiple servo amplifiers, but replacement requires checking the complete drive configuration, connected modules, and braking requirements before installation.

Application Scenarios & Field Pitfalls (The Engineer’s Perspective)
Engineering Pain Point
A CNC machine stops during a production cycle with multiple servo amplifiers showing undervoltage or DC bus faults. The individual drive modules test correctly, but the shared power supply section cannot maintain the required DC bus level.
This is a common failure pattern in modular servo systems. The TVD power supply is the foundation of the drive rack. Aging capacitors, mains issues, cooling problems, or braking circuit faults can interrupt the entire motion system.
Typical Applications
- CNC Machine Tools – Multi-axis servo control for machining centers, lathes, and grinding equipment.
- Automotive Manufacturing – Robot cells, transfer systems, and precision assembly equipment.
- Packaging Machinery – Coordinated motion systems requiring multiple servo axes.
- Industrial Automation Lines – High-speed positioning systems using Indramat TDM/TDA/KDA drive modules.
Technical Pitfalls to Avoid
- Verify DC Bus Compatibility
Confirm that the replacement power supply matches the connected servo drive modules. The TVD1.3-15-03 provides a 320VDC bus; incompatible drive hardware can create startup faults.
- Check Regeneration Requirements
The internal bleeder handles regenerated energy within specified limits. Applications with heavy braking cycles may require additional braking components.
- Inspect Mains Connection Components
The TVD module works with associated mains connection hardware such as NAM modules, chokes, and capacitors. Replacing only the supply unit may not resolve faults caused by upstream components.
