Product Description:
The TDM 1.2-050-220/300-W0 is a servo drive module manufactured by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It converts a fixed mains supply into a controlled three-phase output that regulates torque and speed for Indramat permanent-magnet motors used in handling, pressing, and packaging lines. The unit interfaces with higher-level CNC or PLC controllers through standard command and status lines, forming the power stage of a closed-loop motion axis in industrial automation. In normal operation, this arrangement allows the drive to respond quickly to changing load conditions while supporting stable motor control during acceleration, deceleration, and steady-state motion.
This module supplies a continuous phase current of 45 A, allowing it to deliver up to 15 kW of output when paired with the matching motor. Internally, switching and conduction losses are limited to 250 W, so cabinet ventilation remains manageable. Protection against solid object ingress is classified as IP10, which is suitable for installation in enclosed electrical bays. A dedicated fan rated at 30 VA maintains airflow across the heat sink, and the ready relay can forward system-enable signals as long as its contacts do not exceed 24 V/1 A max. Users may trim motor torque because the drive can be adjusted down to a minimum current setpoint of 15 A. For the control electronics, the external ±15 V reference line draws 15 mA, while the internal regulators consume 140 mA on the positive rail and 60 mA on the negative rail.
The drive’s monitor output is scaled at 0.050 V/A, which makes it easier for the control system to observe current during operation. Reliable operation is permitted up to 1000 m above sea level; at greater heights, reduced air density lowers cooling effectiveness and the module must be derated. The housing has a mass of 10 kg and meets insulation category C, so the panel structure must support the unit securely. Adequate mounting support also helps maintain stability in multi-axis assemblies exposed to machine vibration.
