Product Description:
The TDM 4.1-020-200-W0 is a drive controller produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. It conditions DC bus power for permanent-magnet servo motors, allowing higher-level motion controllers to close position, speed, and torque loops with precision. Mounted in Euro-card racks inside multi-axis cabinets, the module supplies regulated energy to machine tools, packaging lines, and gantry systems that require coordinated motion control. This arrangement separates the motion controller from the power electronics, allowing multiple axes to share a cabinet structure while each motor channel is regulated independently.
Continuous output current is 15 A, enabling the axis to maintain load torque during normal duty. For brief acceleration peaks, the module permits a type current of 20 A, giving the drive additional short-term current capacity before returning to nominal operation. The common DC link is rated at 200 V DC, so the connected power section must operate within that bus level. Thermal control depends on natural convection, which means the enclosure needs unobstructed upward airflow inside the cabinet rather than fan-driven cooling. Its protection class of IP10 helps prevent accidental contact with live parts while leaving the heat sink exposed to room air for heat dissipation.
The drive remains functional from 5 °C up to 55 °C, so cabinet temperature must stay within that range during operation. With a mass of 8 kg, the module adds a notable static load to the mounting structure, and the rack or card cage must support that weight in multi-axis layouts. Stable mounting is important because the module is typically installed beside other drive cards, where combined weight and thermal spacing affect cabinet layout. Open vertical air paths above and below the unit help rising air move past the housing during continuous operation. Panel heaters or additional cabinet ventilation may be required when the surrounding area regularly approaches either end of the allowable temperature range.
