TDM 4.1-020-300-W0/S100

The Bosch Rexroth Indramat TDM 4.1-020-300-W0/S100 from the TDM Servo Drive Modules series features a Type Current of 20 A and a Link Circuit rated Voltage of DC 300 V to deliver precise servo control. Manufactured by Bosch Rexroth Indramat, this drive module leverages Natural Convection cooling to maintain optimal thermal performance in enclosed control cabinets. The unit's integrated electronics handle feedback directly within the module, supporting three-phase synchronous motors with permanently excited rotors. With a compact footprint and straightforward integration, it easily mates to MAC 21, MAC 25, and MAC 41 servomotors for high-dynamics and high-precision applications.

Reliability is assured by a 20 A peak current rating and a 15 A continuous current rating, while the Rated Connection Voltage for Built-in Fan is purposefully Dropped with Natural Convection to simplify wiring and reduce moving parts. The drive meets Class C insulation standards per DIN VDE 0110, and its industry-grade Bb LED indicator flashes green to signal fault-free, power-off status. Custom logic is embedded via an S100 plug-in programming module matched to the motor's resistor and capacitor values, and the module's unique Custom Design Code S100 ensures consistent performance across every unit. Integrated E1/E2 differential inputs and E3/E4 summing inputs optimize speed and torque control when operating in both stand-alone and master-slave configurations.

Installation and maintenance are streamlined by a minimum clearance requirement for heat circulation, and each drive ships in military-grade foam packaging with a one-year backup support and global one-year warranty. The absence of an internal fan follower simplifies preventive maintenance and eliminates bearing wear. Overall, the TDM 4.1-020-300-W0/S100 balances robust power handling with ease of commission, making it ideal for precision CNC, robotics, and automated assembly lines.
