Product Description:

The KMS02.1B-A018-P-D7-ET-ENH-NN-WT-FW near-motor servo drive is produced by Bosch Rexroth Indramat for the KMS Electronic Drives series. Mounted close to the axis, it supplies regulated power and processes feedback in automated handling, packaging, and processing lines. This arrangement keeps the drive electronics near the motor and helps reduce long cable runs in decentralized machine layouts. The unit is design version 1 with a basic performance level, making it suitable for standard motion duties.

The electrical section is rated for a continuous phase current of 5.8 A at a 4 kHz PWM carrier, and short-term current can rise to 17.7 A during starting or braking. An internal bypass channel rated at 25 A returns fault energy to the supply, and the input side draws 7.3 A under nominal load. The intermediate circuit operates at 750 V DC, and a bus capacitor of 0.02 mF helps smooth ripple and buffer recovered energy between switching events. Cooling is provided by natural convection, and total heat dissipation is limited to 50 W, which supports installation outside a conventional control cabinet.

For field installation, the housing has a protection rating of IP65, which helps keep dust and low-pressure water jets away from the electronics. Two coded circular ports provide the network connection through 2 × M12 sockets, and a dedicated Hiperface channel handles encoder feedback from the attached motor. An angular connector option eases cable routing, and the functional series designation is 02. Fault protection includes a short-circuit withstand of 42 kA rms, allowing upstream protective devices to clear high-energy faults. The assembly weighs 2.50 kg, and the unit has no integrated safety options, so external STO or emergency-stop hardware is required when those functions are needed.
