Product Description:

The TDM1.2-050-300-W1-S0102 servo drive module is produced by Bosch Rexroth Indramat as part of the TDM Servo Drive Modules series. It converts the fixed DC link voltage from a supply unit into a regulated three-phase output for MAC synchronous motors, enabling precise speed and torque control in assembly lines, packaging stations, and material-handling axes. By integrating power electronics, signal conditioning, and diagnostics into a compact housing, the unit helps streamline cabinet layout within multi-axis automation cells.

The drive delivers a continuous output current of 45 A, supporting sustained motor torque up to its thermal design limits, while a continuous power rating of 15 kW indicates the maximum sustained output without derating. Regulation originates from a DC link held at 300 V; this voltage is stabilized by upstream supply modules and allows fast current rise times. Short-term overloads are managed by a peak current ceiling of 50 A, and the matching type current supports standardized fuse and cable sizes. Heat generated by switching losses is removed through a built-in fan, keeping semiconductor junctions below critical temperature and containing overall power loss to 250 W. The Humidity Class F designation confirms varnish and insulation tolerances for environments where moisture can reach moderate levels.

Auxiliary circuits are powered by external ±15 V rails; the module can source 15 mA on each rail for encoders or sensors and draws 60 mA at -15 V and 140 mA at +15 V for its own logic functions. These low currents minimize loading on the control supply. Installation is permitted up to 1000 m above sea level without cooling correction. The enclosure has an IP 10 rating, which provides basic protection against accidental contact inside a closed cabinet. With a mass of 10 kg, the unit can be mounted on standard backplanes without additional bracing.
