Product Description:

The KMS02.1B-A018-P-D7-ET-ENH-SD-NN-FW is a near-motor servo drive produced by Bosch Rexroth Indramat and assigned to the KMS Electronic Drives series. This unit carries series designation 02 and design version 1, identifying its generation within the product line. Deployed close to the actuator, it converts DC bus energy into phase-controlled power for compact motion axes in machines. Multi-Ethernet master communication links it to higher-level controllers, while a Hiperface encoder interface returns position data from the motor. These features, combined with the Basic performance level, let the drive execute precise speed and torque loops without a remote cabinet-mounted amplifier.

During continuous operation, the drive outputs 5.8 A to the motor windings, which indicates its thermal limit under nominal conditions. For short transients, it can supply up to 18 A and route 25.0 A through the internal bypass path, protecting semiconductors from overcurrent faults. The internal DC link holds 0.02 mF of capacitance and is charged to 750 V DC, and this energy reservoir supports torque surges and stabilizes the power stage. With a 2.2 kW drive power capability and a rated input of 7.3 A, the converter achieves a voltage-to-current conversion factor of 0.71 × UDC at the output terminals. The dv/dt limiter holds edge steepness to 5.00 kV/µs, reducing insulation stress on the motor, while the control electronics consume 17.5 W of auxiliary power.

Heat is removed by natural convection, and at full load the electronics dissipate 50.00 W, allowing the housing to stay within limits without fans. The sealed aluminum enclosure carries an IP65 rating, so the unit can be mounted directly on machine axes exposed to dust or water jets. Safe Motion circuitry provides integrated monitoring that meets machinery safety requirements without external relays.
