Product Description:

The TDM 3.2-020-300-W0 servo drive module is produced by Bosch Rexroth Indramat as part of the TDM Servo Drive Modules series. Intended for cabinet mounting, the module converts regulated DC link energy into controlled armature current for motor phases, providing closed-loop speed and torque regulation in automated production lines, packaging stations, and material-handling gantries. Through its internal current loop and velocity monitor, it enables precise axis control while occupying minimal panel depth, making it a common choice for multi-axis drive racks used in industrial automation cells.

During continuous duty, the power electronics supply 15 A of motor current. The link is energized by 300 VDC, so the drive expects a rectified three-phase bus at that level before it can modulate output. At a commanded speed of 2000 rpm, the internal regulator blends measured current with tachometer feedback to stabilize shaft velocity. Heat produced by the switching elements is removed solely by natural convection, eliminating the need for external fans. Under nominal loading, the converter dissipates 110 W, which must be considered when planning enclosure airflow. An IP10 housing provides basic finger protection but no sealing against dust or fluids, limiting placement to clean, sheltered cabinets.

Transient events such as machine acceleration are supported by a peak phase demand of 20 A, giving the controller headroom for short bursts without violating device limits. Operation is permitted at ambient temperatures up to 55 °C, so any passive cooling path must keep the internal temperature rise within the permitted range. Operation is also permitted up to 1000 m above sea level, and installations above that height require current derating. A 0.375 V/A current command ratio simplifies analog interface scaling, and the 400 mA logic draw taken from the +24 V rail must be considered when sizing the auxiliary supply.
