Product Description:

The TDM 1.3-100-300-W1-000/S102 servo drive module is built by Bosch Rexroth Indramat and belongs to the TDM Servo Drive Modules series. It is designed to modulate current and DC bus voltage for Indramat servo motors, providing closed-loop speed and torque regulation in automated machinery. By integrating power conversion, control electronics, and protective circuits in a single housing, the unit simplifies cabinet wiring while delivering the motion control needed for packaging lines, material-handling axes, and similar industrial equipment. The module is suited for applications that require repeatable response during acceleration, deceleration, and steady-speed operation.

Thermal management is handled by a built-in fan; airflow is driven by an internal supply, so no external fan power line is needed. The power section operates from a link circuit maintained at 300 V DC, and the converter can supply up to 100 A to the motor windings during commanded acceleration. Control electronics draw auxiliary power from the ±15 V and +24 V rails; the -15 V rail requires 60 mA, the +15 V rail needs 140 mA, and the +24 V rail supports I/O loads with 400 mA. A start-lockout circuit prevents unintended energization and releases only after the enable signal is present and the safety inputs are cleared. The acknowledgment contact is a make contact, so continuity is reported only when the power stage is ready.

The acknowledgment output can switch loads up to 24 V, 1 A, allowing direct interface with external interlock relays. During a trip, the start-lockout coil draws 20 mA, and with a dissipation of only 0.5 W it adds little heat to the control section. Full lockout is reached in less than 0.2 s, which helps stop commanded motion quickly after a fault. This response helps remove drive readiness before motion can continue unintentionally.
