Product Description:

The LTE12 0 608 750 001 is a servo amplifier manufactured by Bosch Rexroth Indramat and assigned to the LTE Servo Amplifiers series. In automation cells, it conditions DC power and modulates current so that servo motors receive accurately timed output for position, speed, and torque control. By housing the drive electronics and protective circuitry in a single unit, the amplifier keeps cabinet integration compact and supports mid-power motion axes in industrial equipment.

The drive delivers a continuous motor phase current of 3 A and can supply up to 12 A for short acceleration bursts before thermal limits intervene. Its internal DC bus presents 310 VDC, generated from the rectified mains, so connected motor insulation and feedback devices must tolerate that voltage. Total apparent power is rated at 0.6 kVA, which is useful when sizing the incoming electrical supply. Carrier modulation allows output frequencies to reach 500 Hz, enabling precise control of high-speed servo motors with low rotor inertia. A control relay draws only 24 VDC from the machine supply with a coil current of 100 mA, which separates low-level control wiring from the higher-energy power stage. Protective Earth bonding is required, and the enclosure has an IP40 rating, so it helps block solid objects such as tools and wires but is not sealed against water or fine dust. Cable runs between the amplifier and motor must not exceed 30 m to keep voltage drop and reflected-wave effects within acceptable limits.

The chassis occupies a footprint of 125 mm in width, 298 mm in depth, and 266 mm in height, so it fits standard 300 mm deep control cabinets while leaving the front panel accessible for diagnostics. Weight is held to 11 kg, which keeps installation handling manageable without special lifting equipment. For convection cooling, a minimum bottom clearance of 100 mm is required, and the installation site must remain below 2000 m altitude because reduced air density can lower cooling performance.
