Product Details:

REXROTH 6KP1143040X9B1 belongs to Indramat KP series single-axis servo drive. The suffix X9B1 represents special hardware variant and dedicated firmware version. Rated three-phase supply voltage 400V AC, high power grade, integrated power stage and motion control logic board, DIN rail cabinet mounting structure. This legacy drive is discontinued, available stock are refurbished spare units for heavy-duty CNC machine tools and automotive nutrunner tightening production lines.

This servo drive realizes closed-loop torque, speed and position control according to the command signal sent by upper CNC or motion controller. It supports high-resolution encoder signal acquisition, high-bandwidth current loop regulation and feedforward dynamic compensation. It can be matched with Indramat synchronous servo motors with absolute or incremental encoder. Shielded power cable and feedback cable reduce electromagnetic interference generated by adjacent servo units and harsh workshop environment.

The power section adopts high-power IGBT module, built-in braking chopper circuit, forced air cooling by built-in fan. Class F internal insulation. It integrates complete protection functions: overcurrent, overvoltage, undervoltage, overtemperature, motor stall and encoder signal loss. Front LED indicators display power ready, running status and fault alarm codes.

All units pass function testing, encoder feedback test, current loop calibration and long-time running aging test before shipment, to guarantee stable performance under continuous multi-shift heavy-load industrial production.

It is widely used on large CNC machining centers, powertrain bolt tightening stations and heavy metal forming equipment. Typical application scenarios include single-axis high-power motion control, spare replacement for aging Indramat KP drive systems and old machine tool retrofit. Automation integrators select this Rexroth drive for its special X9B1 variant configuration and high-power closed-loop motion control capacity.
