Product Description:

The TDM1.3-050-300-W1 is a servo drive module manufactured by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. As a rack-mounted converter, the unit supplies regulated DC power and closed-loop control signals to Indramat AC servo motors, allowing velocity and torque regulation in machining centers, packaging lines, and transfer systems. It forms part of a modular drive stack where each module shares a common DC bus and communicates with higher-level motion controllers through discrete and serial interfaces. This arrangement supports coordinated axis control while keeping the drive hardware concentrated inside a central cabinet.

With a body length of 373 mm, the module occupies a fixed slot depth inside the cabinet while an overall footprint of 390 mm in length, 105 mm in width, and 355 mm in height sets clearance around adjacent electronics. The internal power section is energized from a common DC link held at 300 VDC. Heat is extracted through an aluminum rear channel that rises 325 mm, and the manufacturer specifies a free air gap of 80 mm above this cooling section to maintain rated current capability. System wiring is separated into three plug-in blocks: a feedback connector that carries position data across 10 dedicated pins, a signal bus header with 12 pins for enable, fault, and reference lines, and a 15-pin function strip that routes auxiliary logic and brake control. This connector layout keeps motor feedback, control wiring, and auxiliary functions clearly separated inside the rack.

A 24 V logic rail feeds the control electronics, and the board draws a steady 350 mA, so a compact power supply is adequate for several axes. For safety, the drive will not release its gating circuits until the interlock reaches 24 VDC, preventing accidental energization while the system is being handled. Power cables land on copper M5 and M6 studs, and correct torque of 3 Nm on the M5 hardware and 5 Nm on the M6 hardware secures low-resistance joints under vibration. The separation between low-voltage control power and the main power connections helps keep wiring organized within multi-axis installations.
