Product Description:

The KMS02.1B-A018-P-D7-ET-ENH-L3-WT-FW belongs to the KMS Electronic Drives series manufactured by Bosch Rexroth Indramat. It is a near-motor servo drive in Series Designation 02 and Design Version 1, intended for decentralized axis control in packaging, gantry, and handling machines. The sealed housing allows direct mounting on the machine frame instead of inside a central cabinet. By converting a shared DC link into phase-modulated outputs, the unit reduces cabinet wiring and supports straightforward motion control on distributed axes with integrated safety functions.

Energy for the inverter is held on a DC link rated at 750 V DC and buffered by a 0.02 mF bus capacitor. The power stage supplies up to 17.7 A at a 4 kHz carrier and sustains a continuous limit of 18 A; these values set the thermal limit when cooling is provided by natural convection. A dv/dt of 5.00 kV/µs reduces voltage stress on motor insulation during switching. Command traffic enters through Multi-Ethernet master communication and passes through an output coupling with two M12 ports for daisy-chain wiring. A Hiperface encoder interface closes the speed loop, the rated input current is 7.3 A, and an angular connector option helps in tight machine spaces.

During regeneration or braking events, the bypass path carries up to 25 A, and the short-circuit withstand rating of 42000 A rms coordinates with upstream protection devices during fault conditions. Internal losses are limited to 50.00 W, so the drive adds only a moderate heat load to surrounding machine structures and nearby components. The IP65 enclosure protects the electronics against dust and water jets, and Safe Torque Off helps prevent unintended motion when torque must be removed. This arrangement supports distributed servo installations where the drive is mounted close to the motor rather than in a sealed control cabinet.
