Product Description:
The KMS01.2B-A018-P-D7-SE-ENH-NN-NN-FW is a near-motor servo drive produced by Bosch Rexroth Indramat for the KMS Electronic Drives series. Positioned directly on the machine frame, it provides closed-loop control for compact servo motors while reducing the amount of cabinet wiring required elsewhere in the system. The unit is suitable for decentralized motion axes in demanding factory environments because its sealed housing helps protect the electronics from dust and water spray. It converts DC link energy into controlled three-phase output so torque and speed can be regulated in assembly, packaging, and material-handling equipment.
The internal DC link is rated at 750 V DC and is buffered by a 0.02 mF capacitor to support stable energy storage during rapid duty cycles. Continuous motor output is supplied at 5.8 A RMS, while short acceleration demands can rise to 17.7 A without changing the basic operating concept of the drive. The rated input current is 7.3 A, so upstream power distribution must account for that load during normal operation. A phase-to-phase dv/dt of 5 kV/µs means the motor cable insulation must be suited to fast switching edges. Heat is removed by natural convection, so the unit does not require a fan for routine cooling.
During regenerative events, the power stage can channel up to 25.0 A, which helps the drive manage temporary current flow when energy returns from the motor. Master control communication uses SERCOS (RS422), allowing deterministic data exchange between the controller and the drive. Encoder feedback is handled through Hiperface over a 7.5 m cable that carries 1 Vpp analog signals and a 12 V sensor supply. The enclosure weighs 2.40 kg, which supports direct installation close to the motor and helps keep overall cable routing compact. This placement also reduces the distance between the drive and the axis it controls.
