Product Description:

The TDM 3.3-020-300-W0 servo drive module is produced by Bosch Rexroth Indramat and belongs to the TDM Servo Drive Modules series. It converts direct-current bus energy into controlled three-phase outputs that command associated motors, making it an integral element in automated packaging lines, machine tools, and material-handling cells. By executing velocity and torque instructions delivered from a higher-level PLC, the unit ensures repeatable axis movement and supports feedback scaling and interlock features required for safe industrial operation. Its narrow housing allows dense cabinet layouts without restricting service access.

The drive accepts bus power at 300 VDC and delivers a continuous armature current of 15 A; momentary overloads are handled with a peak capability of 20 A. Nominal mechanical output is regulated to an operating speed of 2000 rpm, and the built-in analog monitor provides current feedback scaled at 0.375 V/A for quick diagnostics. A start-lockout circuit rated at 20 mA and 0.5 W prevents inadvertent energization until the controller is enabled. The ASQ relay contacts can switch 24 V at 1 A, while field wiring on the X8 terminal is secured with 3 Nm of tightening torque. Cabinet integration is aided by a 70 mm width, 390 mm height, and 325 mm depth that match standard 19-inch rack clearances.

The speed feedback inputs accommodate varied tachogenerator sensitivities through scaling factors of 200 rpm/V on channels E1 and E2, 300 rpm/V on E3, and 150 rpm/V on E4, so a single module can match several motor feedback devices without recalibration. At the output lugs, the drive permits fastening torque up to 5 Nm, protecting conductors from vibration loosening. These input options let the drive work with different motor feedback arrangements while maintaining stable speed-loop response.
