Product Description:
The 0 608 750 111 servo amplifier is produced by Bosch Rexroth Indramat and belongs to the LTU Servo Amplifiers series. Designed for industrial automation, the module converts DC-bus energy into three-phase AC so that matched servo motors receive precise current and voltage profiles. In a motion system, it forms the link between the low-level controller and the motor windings, translating velocity or torque commands into regulated power while monitoring feedback to maintain closed-loop operation. This arrangement allows the controller to manage motor behavior accurately without driving the power stage directly.
The unit accepts a logic supply of +24 V / -24 V / 5 V, separating control electronics from the power stage for noise immunity. Its internal DC link can climb to 320 VDC, and that energy is switched at rates that allow an output frequency up to 1000 Hz, supporting fast motor response and fine commutation. The inverter generates up to three sinusoidal phases with a maximum line-to-line voltage of 230 VAC. It can deliver a peak current of 50 A for acceleration or shock loads, while a continuous current of 12 A supports steady-state operation and sets the thermal limit for ongoing use.
The amplifier remains operational up to 55 °C, so the ambient temperature inside the control enclosure must stay below that limit. A protection class of IP20 indicates finger-safe openings but no splash sealing, so the unit must be installed inside a cabinet rather than on exposed machinery. Radiated and conducted emissions meet EN 55011 Class A, and immunity levels reach IEC 1000-4 Parts 2-5 Level 4 for operation in industrial electrical environments. The housing measures 46 mm in width, 285 mm in depth, and 271 mm in height, and the mass of 2.85 kg allows straightforward panel mounting while keeping the assembly relatively easy to position in a multi-axis rack.
