Product Description:

The TDM 7.1-015-300-W0/S102 is a servo drive module produced by Bosch Rexroth Indramat and assigned to the TDM Servo Drive Modules series. In automated machinery, the unit converts a stabilized DC link into controlled three-phase power for matched Indramat servo motors, enabling precise velocity and torque regulation. It fits into modular drive racks, where its signal supplies and feedback channels allow a higher-level controller to command axis motion without separate power stages. This layout supports compact drive assemblies used in packaging, printing, and material-handling equipment.

This drive operates from a DC bus of 300 VDC, and a tolerance band of ±10% allows the internal regulators to accommodate common supply variation without nuisance trips. During acceleration or braking events, the power stage can draw up to 15 A, while a continuous current of 8 A is the steady-state limit for normal thermal operation. With a continuous power capability of 4.5 kW, the module suits mid-frame motors that run for extended periods under consistent load. Its rack-based format also supports orderly integration with control electronics and motor feedback connections in centralized machine cabinets.

Its internal losses are rated at 90 W, and natural convection cooling requires clear airflow around the module so heat can leave the enclosure effectively. The housing has an IP 10 rating, so the unit should be installed inside a closed electrical cabinet to limit exposure to debris and accidental contact. Reliable operation is permitted at ambient temperatures up to 45 °C, with output derating above that point. The permitted mounting height reaches 1000 m above sea level before additional thermal adjustment is needed. Additional operating details include humidity class F, auxiliary signal supply rails of +24 V, +15 V, and -15 V for encoder and logic functions, a maximum reduced-rating temperature of 55 °C, and a shipping weight of 6.5 kg.
