Product Description:
The TCM 2.1-01-7 is a capacitor module manufactured by Bosch Rexroth Indramat and supplied in the TCM Capacitance Modules series. Designed for connection to the DC link of Indramat inverter systems, the unit stores electrical energy so sudden load changes do not destabilize bus voltage. By absorbing regenerative peaks and releasing charge during acceleration phases, it supports stable drive operation in industrial automation cells with frequent speed shifts and braking cycles. It is installed inside the control cabinet alongside power supplies and servo drives, and its passive design allows it to operate without active communication hardware, which simplifies cabinet integration in multi-axis systems.
The module has a capacitance of 1 mF, allowing it to smooth moderate energy fluctuations on medium-power axes. Its overall dimensions are 355 mm in length, 105 mm in width, and 208 mm in height, which match the footprint of Indramat power sections so the units can mount on the same plate. Power leads connect to threaded posts sized M5, making them compatible with standard ring lugs and supporting low-resistance connections to the DC bus. When tightened correctly, the terminals hold the conductor securely and help prevent deformation or hot spots during normal operation.
Connection safety depends on a tightening torque of 2.5 Nm, which helps prevent loosening under vibration common in press or gantry frames. The copper bars are separated by a center-to-center distance of 60 mm, giving enough room for insulated lugs and reducing the chance of arcing. An integral contact guard measuring 18 mm sits above the live hardware to deter accidental contact, while installation requires a minimum clearance of 80 mm around the housing to preserve convective cooling paths and allow safe access. These spacing requirements also help keep wiring orderly inside crowded control cabinets.
