TDM3.3-030-300
The TDM3.3-030-300 from Bosch Rexroth Indramat is a high-performance module within the TDM Servo Drive Modules series, engineered for precise control of MAC three-phase servo motors. This compact drive delivers a rated Continuous Current of 25A and handles a Link Circuit d.c Voltage of 300V, ensuring robust operation across demanding industrial applications. Designed to manage up to Peak Current peaks of 30A and provide a continuous output of 9 kW, the drive balances power density with operational stability. Certified to Insulation category Class C in accordance with DIN VDE 0110 and tested for Humidity Classification F under DIN 40 040, this module meets stringent reliability and safety standards. The module’s Protection class IP10 rating and a compact Weight of 8 kg simplify installation in confined control cabinets.
Featuring advanced electrical and thermal design, the TDM3.3-030-300 maintains high efficiency with a measured Power loss with continuous current of just 175 W. Its architecture supports precise current loop modulation, enabling rapid torque response and positional accuracy. The drive’s internal protection against overvoltage, overcurrent and thermal overload safeguarding maximizes uptime. Insulation and humidity ratings ensure stable performance in environments subject to temperature fluctuations and moisture, while the rugged IP10 enclosure shields sensitive circuitry from incidental contact. Engineers benefit from a wide input voltage window and programmable parameters via the MOD plug-in module, facilitating motor matching without hardware changes.
Operational versatility is inherent in the drive’s design: it supports variable-speed control loops in NC machine tools, transfer lines and complex automation systems. The robust Insulation category Class C construction allows continuous operation at elevated temperatures, while the Humidity Classification F rating provides resilience against ambient humidity. With a Weight of only 8 kg and a maximum permissible installation height of 1000 meters above sea level, the unit adapts to both central control rooms and distributed installations. Low power dissipation through efficient thermal management reduces enclosure cooling requirements and extends mean time between failures. Maintenance is simplified by clear LED diagnostics and status lamps, enabling rapid troubleshooting and minimizing downtime.
Integration of the TDM3.3-030-300 is seamless in CNC metalworking and woodworking machinery, robotic assembly lines and automotive production cells. It interfaces directly with Bosch Rexroth Indramat MAC synchronous motors using a standardized MOD plug-in interface for automatic parameter loading. The drive’s combination of 9 kW performance, precise current control and built-in safety compliance makes it ideal for high-precision servo applications. Engineers can deploy this module in new installations or retrofit existing equipment to enhance dynamic response and throughput.
