Product Description:
The TDM 7.1-015-300-W0 is a servo drive module built by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. It interfaces with permanent-magnet motors to regulate torque, speed, and position loops in industrial automation cells where cabinet-mounted converters supply DC power to multiple axes. By modulating motor current, the unit supports commanded motion profiles in material handling, printing, and assembly stations. The module is intended for cabinet-based multi-axis systems that use a shared power source and separate control electronics for coordinated motion.
This module delivers a continuous output of 8 A, allowing sustained operation without exceeding the thermal limits of the power stage. Its DC link is stabilized at 300 VDC, so upstream supply sections can share a common intermediate circuit while the current regulators operate with predictable voltage headroom. Heat is removed through natural convection cooling, which eliminates forced-air components and simplifies enclosure airflow. For brief accelerations or load shocks, the power section tolerates a 15 A peak current before protective cutback engages. Internal dissipation reaches 90 W, which helps determine passive heat paths and allowable cabinet temperatures.
The output stage supports motor applications up to 4.5 kW as long as ambient temperature does not exceed the 55 °C reduced-rating point. With an IP10 housing, the module is intended for closed electrical cabinets that shield the electronics from direct contact and larger foreign objects. Functional operation is permitted up to 1000 m above sea level, and derating is required beyond this height because lower air density reduces convection. The drive weighs 6.5 kg, which supports installation on DIN rails or mounting plates. Additional data include humidity class F and control-electronics supplies of +24 V / 250 mA, +15 V / 150 mA, and -15 V / 75 mA. These auxiliary control voltages support the internal signal-processing section rather than the motor power output.
