Product Description:

The TDM 2.1-36-300-W0 is a servo drive module created by Bosch Rexroth Indramat and used in the TDM Servo Drive Modules series. It functions as the power interface between a plant-level DC supply and the servomotor field wiring, allowing closed-loop motion axes to accelerate, brake, and hold position under digital control. In automated transfer lines, presses, or packaging cells, this unit converts shared DC bus energy into regulated three-phase output while also forwarding feedback and command signals to the higher-level controller.

Its type current reaches 36 A, so the drive can support rapid torque transients without saturating the power stage. The link circuit is designed around a 300 VDC bus, which sets the operating voltage for regenerated energy and the downstream three-phase bridge. Heat is removed through natural convection, so installation must leave vertical space for airflow and does not require an auxiliary fan assembly. Motor phases are delivered as a three-phase output to maintain balanced excitation across the stator coils. Connection to the energy bus is routed through the X1 connector, which helps keep cabinet wiring organized.

DC power arrives on the dedicated L+, L- busbar, keeping the high-current path separate from logic conductors. Velocity and position commands enter through the multi-channel setpoint block labeled E1-E2, E3, E4, which accepts differential analog references from the motion controller. Discrete field wiring, including end-of-stroke switches, lands on the X5 user I/O header so sensor loops remain separate from power conductors. Resolver or encoder information returns through the X6 feedback connector to close the control loop. Because the module has no built-in fan voltage supply, ambient conditions must remain compatible with convection cooling.
