Product Description:
The TDM 1.2-100-300-W1-220 is a servo drive module produced by Bosch Rexroth Indramat for the TDM Servo Drive Modules series. It operates on a common DC bus and regulates armature current for matched MAC servomotors used in automated tooling, printing, and assembly lines. In industrial automation cells, the module serves as the closed-loop power stage that converts motion commands from a CNC or PLC into controlled motor torque and responsive axis movement. Because it works as the current-regulating section of the axis, the drive supports smooth response during speed changes and positioning tasks.
During operation, the drive can furnish a continuous armature current of 65 A and momentary surges up to 100 A, which helps it support rapid acceleration and changing load demand. That current is supplied from a link circuit maintained at DC 300 V. Under rated conditions, the module delivers up to 30 kW of electrical power while dissipating 400 W as heat. Heat is removed by an integral blower, and the specified cooling method is forced ventilation. The blower consumes 30 VA and is protected by an internal 0.315 A/250 E fuse. Insulation category C and protection type IP 10 suit enclosed cabinet mounting where only basic contact protection is provided.
The analog command interface uses a scaling factor of 0.050 V/A, so monitor readings track motor current in a simple and direct way. For smaller axes, the current setpoint can be reduced to a minimum of 15 A to help limit motor heating during adjustment and low-load operation. The control electronics use the ±15 V auxiliary rails, drawing 60 mA from the -15 V side and 140 mA from the +15 V side. This arrangement separates low-level control power from the higher-energy motor circuit inside the cabinet. The axial-flow fan is powered by AC 220 V. With an installation weight of 10.5 kg, the module can be mounted on standard 24-inch cabinet rails without extra support hardware.
