Product Description:

The Bosch Rexroth Indramat KMS02.1B-A018-P-D7-ET-NNN-L3-TO-FW is a near-motor servo drive in the KMS Electronic Drives series. As a Series Designation 02 unit with Design Version 1, it mounts close to the actuating motor to minimize cable length and reduce electromagnetic noise in distributed automation cells. The drive handles local velocity and torque loops for compact actuators on packaging, material-handling, and assembly lines.

The drive operates from a DC 750 V bus and draws a rated input current of 7.3 A to sustain an output stage capable of 5.85 A continuous motor current. Passive natural convection cooling dissipates heat through the finned aluminum case, which weighs 2.50 kg, so no fans or liquid lines are required. Internal losses are limited to 50 W, which helps limit enclosure temperature rise during full-load duty. The sealed electronics carry an IP65 ingress rating that blocks dust and low-pressure water jets. Electromagnetic compliance is classified under EMC Category C3, and the M5 ground lug provides the protective earth path. The performance level is Basic and is suited to applications that need core speed and torque regulation without advanced motion functions.

Control electronics receive 17.5 W of rated control power that is galvanically isolated from the main DC link, helping keep logic stable during transients. The power stage tolerates up to 25 A of through current for short acceleration bursts, and Safe Torque Off removes drive energy when the safety circuit is triggered. An integrated node supports Multi-Ethernet protocols, and the optional output coupling can daisy-chain additional axes without extra switches. Because the unit is supplied without an encoder interface, feedback must be provided by a motor-mounted sensor or an external device. Protective components are rated for a prospective short-circuit current of 42000 A rms, matching feeder ratings used in large industrial panels.
