Product Description:

The KMS02.1B-A018-P-D7-ET-NNN-NN-NN-FW is a near-motor servo drive released by Bosch Rexroth Indramat within the KMS Electronic Drives series. Placed directly on the machine frame, the unit supplies regulated power to a matching servo motor and reduces the length of the motor cable run. This arrangement supports modular machine sections where each axis is mounted close to its load. Its decentralized location helps distribute axes without large control cabinets, which can simplify wiring and improve electromagnetic compatibility in automated production cells.

The enclosure carries a protection rating of IP65, so the electronics remain sealed against dust and low-pressure water jets found on a factory floor. Internally, a compact bus capacitor supports a DC link voltage of 750 V DC, allowing the drive to accept energy from shared supply modules and return regenerative power to the common rail. The power path can conduct up to 25 A of through current toward downstream axes, while its own inverter delivers an output phase current of 5.85 A to the adjacent motor. During operation, switching losses and auxiliary circuits generate approximately 50 W of heat, and natural convection across the finned housing is sufficient to keep component temperatures within range without forced-air cooling.

The control electronics draw 17.5 W from the separate 24 V line, and the incoming mains side is limited to a continuous 7.3 A, which helps when sizing shared power sources. A cast-aluminum body keeps total mass to 2.50 kg, reducing the load placed on mounting surfaces and support brackets. Communication with the main motion controller is handled over Multi-Ethernet, supporting EtherNet/IP, PROFINET, or EtherCAT networks. The basic performance level, the absence of integrated safety functions, and a short-circuit rating of 42 kA rms suit the drive for standard positioning tasks in packaging, material-handling, and assembly lines.
