Product Description:

The TDM 1.3-050-300-W1-00 drive module from Bosch Rexroth Indramat belongs to the TDM Servo Drive Modules series. This unit is a three-phase DC-link servo amplifier used to regulate torque, velocity, and position of Indramat permanent-magnet motors in automated machinery. It translates drive commands into controlled motor current for coordinated axis motion. Filtered mains input supplies the link, and built-in monitoring circuits supervise overvoltage and overcurrent conditions during operation.

It delivers a continuous armature current of 45 A, allowing the connected motor to produce rated torque without derating. Under this sustained load, the module can supply up to 15 kW of mechanical power from a DC bus held at 300 VDC. For transient demands such as acceleration or shock loading, the drive can rise to a peak current of 50 A, and this short-term margin accommodates dynamic loads without triggering protective shutdown. The control electronics and switching devices dissipate 250 W of heat during nominal operation, a figure that determines airflow requirements in the electrical cabinet.

The module integrates a cooling fan rated at 30 VA, so the declared power loss can be carried away even when the drive is mounted close to other heat sources. Reliable performance is specified between 5 °C and 45 °C, matching the typical temperature range inside sealed control cabinets. Sites operating at higher ambient temperatures must introduce additional ventilation or reduce current. Installations are permissible up to 1000 m elevation before altitude correction factors apply, which preserves full current capability in most lowland plants. The auxiliary logic rails draw +15 V at 140 mA and -15 V at 60 mA for interface electronics, keeping control circuitry separate from the main power stage. With a mass of 10 kg, the drive can be mounted without placing excessive mechanical load on standard control cabinet structures.
