Product Description:
The TDM 1.2-100-300-W1-000/S102 is a servo drive module built by Bosch Rexroth Indramat and supplied within the TDM Servo Drive Modules series. It forms the power stage between a regulated DC bus and a compatible Indramat brushless servo motor, delivering controlled current for positioning and velocity loops in industrial automation cells. By integrating cooling and auxiliary supply functions inside the module, it helps reduce cabinet complexity while supporting the stable motor response needed in packaging, machine tool, and material-handling axes. This type of module is used where the drive amplifier must respond quickly to changing load conditions without interrupting axis accuracy.
Its continuous output capability is 65 A, and the thermal design supports a continuous mechanical power of 30 kW. Energy is taken from a DC link held at 300 VDC. Excess heat is removed by a built-in fan, and under nominal load the converter dissipates 400 W as heat. The unit includes +15 V and -15 V auxiliary rails. The +15 V rail has a 15 mA output with 140 mA consumption, and the -15 V rail has a 15 mA output with 60 mA consumption from the common supply. These rails support analog reference circuits and feedback conditioning, and this arrangement keeps auxiliary functions within the module while reducing external wiring.
Dynamic events such as acceleration spikes are handled by a peak output of 100 A, allowing short bursts of torque without overstressing the power stage. The module remains functional in ambient temperatures up to 55 °C when panel airflow is adequate, and it can be installed at elevations up to 1000 m above sea level without correction. A protection category of IP10 means live parts are shielded against finger contact, so the drive must be mounted inside a grounded enclosure. The unit has a mass of 10.5 kg, which supports manageable installation on DIN rails or directly on a back panel. Open mounting is not suitable because this protection level is intended for installation inside a control cabinet.
