Product Description:

The TDM-1.2-100-W1-S0102 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. Designed to regulate three-phase AC servo motors, the unit converts DC-link energy into controlled armature current so position and velocity loops in automated machinery remain accurate. The module interfaces with higher-level motion controllers and supplies both power and low-voltage services required by Indramat motor families in packaging lines, printing presses, and material-handling cells.

The drive draws +15 V at 140 mA and −15 V at 60 mA from the control rack, and it can source an external ±15 V load of 15 mA for tachometer or resolver electronics. Its link circuit operates at 300 VDC, feeding a continuous motor current of 65 A; under this load, the converter can deliver up to 30 kW of mechanical output. Thermal energy from the power stage is removed by a built-in fan, which helps simplify cabinet airflow design. Mechanical fastening values include a busbar bolt preload of 3 Nm and a motor terminal screw torque of 5 Nm, which helps maintain secure current paths while preventing thread damage. Insulation is classified as category C to tolerate the elevated winding temperatures common in high-power drives, and the unit may be mounted up to 1000 m above sea level without derating. The enclosure has an IP10 protection degree, which indicates guarded live parts but no dust sealing.

During acceleration or shock loads, the module supplies a peak armature current of 100 A, giving machinery brief torque reserve without exceeding semiconductor limits. Internal dissipation is specified at 400 W, and this value works with the fan requirement when enclosure heat is considered. The electronics remain within rating up to an ambient temperature of 55 °C, which suits factory environments that do not have full climate control. At only 10.5 kg, the drive remains comparatively easy to handle during installation, and its modest mass also reduces the burden on rack layout changes.
