Product Description:
The TDM 4.1-030-300-W1-220/S100 is a servo drive module produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It converts direct-current bus power into controlled three-phase output for Indramat servomotors, supplying accurately regulated speed and torque to automated machine tools, packaging stations, and handling axes. By combining power electronics, control logic, and an integral cooling section in one housing, the unit streamlines cabinet layout for multi-axis systems. This arrangement is well suited to coordinated motion systems where several axes share a common cabinet and must respond quickly to changing commands.
The power stage delivers a continuous current of 25 A, supporting applications that require up to 9 kW of output power without derating. Thermal energy is removed through forced ventilation; the integral fan draws 20 VA from a 220 V AC auxiliary line and is protected by a 0.315 A/250 V fuse. Link-circuit energy is maintained at 300 V DC, helping the drive respond quickly to torque changes on demanding axes. Insulation category C withstands the repetitive switching voltages of the IGBT bridge. During steady-state motion, the drive draws a rated current of 30 A, and the internal airflow helps keep the power section within a stable operating range during repeated load changes. The fan adds only 1.17 kg to the assembly, so the module remains suitable for compact cabinet layouts with closely spaced drive hardware.
Total module losses are limited to 175 W, so cabinet airflow requirements remain modest. Reliable operation extends up to an ambient temperature of 55 °C and a mounting altitude of 1000 m before current reduction is necessary. The open-frame construction carries the protection rating IP10, so the drive must be installed inside an enclosure to prevent accidental contact with live parts. With a transport weight of 8 kg, the module fits standard 60 mm rail spacings without additional structural support. The housing format works well in protected control cabinets where several drive modules are arranged side by side and cooled by guided internal airflow.
