Product Description:

The TDM 1.2-050-300-W1-220/S100 is a servo drive module manufactured by Bosch Rexroth Indramat as part of the TDM Servo Drive Modules series. It serves as the power interface between the mains supply and a compatible Indramat servomotor, providing regulated current and voltage so the motor can follow speed or position commands from the machine controller. Installed in a modular rack, the unit handles axis acceleration, deceleration, and holding torque while monitoring internal temperature and supply status. This arrangement lets the module support coordinated servo motion in automated machinery where stable drive response is required across changing load conditions.

The drive delivers a continuous armature current of 45 A and a continuous mechanical power capacity of 15 kW, allowing medium-frame motors to run at full duty without derating. Under these conditions, the converter dissipates 250 W as heat, and the integral blower consumes 30 VA from an auxiliary supply; thermal protection is supported by the F5 0.315A/250E fan fuse on the front panel. Environmental sealing is limited to an IP 10 housing, so the unit must be installed inside a protected cabinet. The design follows Humidity Classification F and Insulation Category C, making it suitable for typical industrial indoor environments.

The module can operate at ambient temperatures up to 55 °C and at elevations not exceeding 1000 m without output reduction. Control circuitry provides a ready relay rated at 24 V, 1 A max for interlock signaling to higher-level control circuits. For measurement tasks, the board provides dedicated supply rails and a monitor output for motor temperature sensing, and the temperature sensor connection includes a 20 kΩ series resistance to protect the logic input. With all accessories installed, the assembly weighs 10 kg, which supports straightforward cabinet mounting.
