XMS2-W0375ANN-01AETT0NNNN-S04RSN1NNNN0NN

The XMS2-W0375ANN-01AETT0NNNN-S04RSN1NNNN0NN is a second-generation, single-axis inverter produced by Bosch Rexroth Indramat for the XMS2 ctrlX Drives series. It forms the power stage of a ctrlX DRIVE cabinet and converts energy from a common DC link into a phase-modulated output for precise motor control. This arrangement supports regulated torque, speed, and position in automated machinery and production cells. The single-axis design allows the inverter to operate one connected motor through commands received from the associated control section.

The unit operates from a nominal DC bus voltage of 750 V and tolerates up to 900 V during regenerative peaks. Its DC bus connection is rated for 300 A to supply the power section under demanding operating conditions. The inverter delivers a continuous output current of 221 A at a switching frequency of 4 kHz and can reach 375 A during dynamic events. An internal capacitance to ground of 2 × 100 nF helps limit high-frequency leakage current. The unit produces 2146 W of power dissipation, which is removed through an internal air-cooling channel. An insulation resistance of 1 MΩ maintains electrical isolation between live conductors and the housing. Multi-Ethernet connectivity and the Sercos III protocol carry real-time setpoints, operating data, and diagnostic information between the inverter and the ctrlX control system.

The drive measures 340.5 mm in height, 196.5 mm in depth, and 250 mm in width. It weighs 18.9 kg, so the cabinet structure must provide suitable support and sufficient clearance for cooling airflow. The housing has an IP20 protection rating when the DC link is energized at 750 V, protecting against accidental contact with hazardous internal components. A control panel is fitted for local access to operating information and settings. The drive is supplied without a motor connector set, allowing the motor conductors to be configured for the installation. The integrated Safe Torque Off circuit disables inverter gate firing to remove motor torque without requiring external power contactors.
