Product Description:
Bosch Rexroth Indramat manufactures the TDM 1.2-050-300-W1-220 as part of its TDM Servo Drive Modules series. This drive converts rectified DC into three-phase output for Indramat servo motors, allowing velocity, torque, and position loops to be closed by the higher-level controller. It is intended for cabinet installation within automated machine tools, packaging lines, and material handling axes where modular drive sections simplify maintenance and reduce downtime.
The power stage delivers a continuous phase current of 45 A, corresponding to a mechanical shaft output of 15 kW when matched with the recommended motors. For transient load steps, it can supply 50 A of peak current, giving additional acceleration torque before thermal limits are reached. Energy is taken from a shared bus at 300 VDC link-circuit voltage; under nominal loading, the module dissipates 250 W as heat, which is removed by an internal fan rated at 30 VA and operated from the 220 VAC auxiliary supply. That fan is protected by a 0.315 A/250 E miniature fuse mounted on the drive motherboard. Control electronics draw 140 mA from the internal +15 V rail, 60 mA from the −15 V rail, and can source 15 mA of external +15 V for encoder or sensor interfaces.
The housing carries insulation category C and a IP10 open-frame protection rating, so installation must occur inside a grounded control enclosure. At only 10 kg, the module can be mounted on standard DIN rails or backplanes. Thermal design allows continuous duty up to 55 °C ambient without derating when the cabinet airflow is unobstructed, and the integrated fan maintains component temperature margins. Reliable commutation is specified for sites situated at elevations up to 1000 m above sea level, beyond which additional cooling measures are recommended to offset reduced air density.
