Product Description:

The LTS350D 0 608 750 125 is a servo amplifier produced by Bosch Rexroth Indramat within the LTE Servo Amplifiers series. Designed for CNC machines, handling systems, and general automation, the unit modulates DC-link energy into a three-phase AC output that matches commanded torque and velocity profiles of synchronous or induction motors. Its compact card-frame construction allows cabinet mounting alongside PLC hardware, providing the regulated power stage that links drive controllers to field actuators.

The power stage supplies a continuous phase current of 12 A and can momentarily deliver up to 50 A during acceleration or rapid position corrections. Carrier modulation supports motor frequencies up to 1000 Hz, enabling high-speed spindle or linear motor operation. The inverter produces a maximum line-to-line voltage of 230 VAC across its 3-phase output, derived from an internal DC link and synchronized with external command signals. Motor leads may extend to 100 m without violating dynamic response or EMC limits, enabling remote mounting of the power electronics. Emissions comply with EN 55011 Class A, and the assembly remains functional up to 55 °C ambient when adequate airflow is provided.

Logic sections draw control power from +24 V/-24 V/5 V, separating the control electronics from the main bus. The DC link operates between a minimum of 220 VDC and a ceiling of 330 VDC, giving the system a clear energy window for regeneration and braking resistor sizing. An IP20 housing that is 46 mm wide, 285 mm deep, and 271 mm high fits standard 19-inch racks, and the 2.7 kg mass allows straightforward handling during installation. Operation is permitted only on clean, dry control-panel air, and three-phase outputs must be routed through properly shielded conduit to maintain the specified immunity margin.
