Product Description:
The TDM 4.1-030-300-W1-115 servo drive module is produced by Bosch Rexroth Indramat within the TDM Servo Drive Modules series. It converts regulated DC into three-phase motor current and supervises feedback signals to command torque and speed in automated machinery. Although compact, the unit carries full drive logic, gate control, and protective monitoring so it can be integrated with MAC servomotors for axes in packaging lines, printing presses, and material-handling systems.
The module draws its logic power from an internal ±15 V and +24 V supply; the −15 V rail supports 60 mA of sensor demand, the +15 V rail delivers 150 mA for analog circuitry, and the +24 V rail supplies 650 mA to control relays. Motor energy comes from a DC link of 300 VDC. Under continuous motion the amplifier can furnish 25 A to the motor, while transient demands are handled by a 30 A peak capability; rated RMS current also equals 30 A for sizing cables. Output power is limited by the design rating of 9 kW, and thermal modeling shows a steady-state drive power loss of 175 W. Enclosure ingress protection is specified as IP 10, so it must be mounted in a closed control cabinet with forced airflow from the integral fan.
The cooling assembly uses a squirrel-cage fan that consumes 20 VA at a supply of 115 VAC; the fan itself weighs 1.17 kg and is pre-installed on the heatsink for quick replacement. Including its sheet-steel housing, the module mass reaches 8 kg, a consideration for panel rail loading during service. Forced ventilation maintains junction temperatures within limit up to the maximum mounting altitude of 1000 m, allowing the drive to sustain its rated currents without derating. The open IP 10 construction also means cabinet dust filtration is required to protect the measuring circuits on the ±15 V and 24 V rails.
