Product Description:

The KMS02.1B-A018-P-D7-ET-ENH-NN-WN-FW is a near-motor servo drive built by Bosch Rexroth Indramat and assigned to the KMS Electronic Drives series. Mounted close to the associated servo motor, it trims cabinet wiring runs while still executing closed-loop speed or position control over a short feedback path. The unit’s basic performance level targets general-purpose automation stages that need compact electronics able to survive plant-floor humidity and airborne oil mist.

The drive’s logic section draws just 17.5 W of control power, so auxiliary supplies remain modest. A shared DC link rated at 750 Volt DC feeds the inverter, supporting energy exchange between adjacent axes. During motion surges the power stage can source up to 18 A of phase current, setting the ceiling for motor torque and thermal loading. An enclosure rating of IP65 protects the electronics from dust and low-pressure water jets, allowing on-machine installation without extra housings. Network integration is simplified by the built-in Multi-Ethernet interface, which can be switched among EtherNet/IP, PROFINET, or EtherCAT through firmware settings rather than hardware swaps.

Link-side energy is smoothed by a bus capacitance of 0.02 mF, limiting voltage ripple during regeneration. The power electronics can convert and disperse up to 50.00 W of heat, and that load is evacuated by Natural Convection, eliminating fans that would otherwise need scheduled maintenance. For safety-critical bypass scenarios, the internal path endures a continuous 25.0 A without exceeding its thermal limit, keeping upstream supplies intact while the axis is isolated. These electrical and thermal allowances complement the earlier current and ingress data by describing how the drive maintains stable operating temperatures and fault tolerance under everyday plant conditions.
