Product Details:

REXROTH 6KP1143005X1B1 belongs to Indramat KP series compact servo drive unit. It is a single-axis servo amplifier designed for matching Indramat permanent magnet synchronous servo motors. The suffix X1B1 represents the hardware variant and default firmware version. Rated supply voltage 3×400V AC, rated output current 12A, integrated power stage and control logic board, standard DIN rail cabinet mounting structure. This legacy drive is discontinued, available stock are refurbished spare units for CNC machine tools and automated tightening stations.

This servo drive executes closed-loop torque, speed and position control according to the command signal from the upper CNC or motion controller. It supports encoder feedback signal collection, current loop high-speed regulation and dynamic feedforward control. It can be matched with Sercos or analog command interface variants. Shielded power and feedback cables reduce electromagnetic interference generated by adjacent servo units and harsh workshop environment.

The drive adopts IGBT power module, built-in braking chopper circuit, Class F internal winding insulation. It integrates full protection functions: overcurrent, overvoltage, undervoltage, overheat, motor stall and encoder signal fault. LED status indicators show power ready, operating status and fault alarm codes. Internal fan forced cooling structure for continuous heavy-duty operation.

All units pass power-on test, current loop calibration, encoder feedback test and dynamic run-in test before shipment to guarantee stable performance under long-time multi-shift industrial production.

It is widely used on CNC machining centers, automotive nutrunner tightening lines, packaging machinery and metal forming automation equipment. Typical application scenarios include single-axis motion control, spare replacement for aging Indramat KP drive systems and old machine tool retrofit. Automation integrators select this Rexroth drive for its compact KP series structure and reliable closed-loop servo performance.
