Product Description:
The XMS2-W0120ANN-01NETT0NNNN-S03RSN1NNNN0NN is a single-axis power inverter produced by Bosch Rexroth Indramat within the XMS2 ctrlX Drives series. In an automation cell, it converts a stabilized DC bus into three-phase output for a servomotor, allowing motion controllers to regulate speed, position, and torque without a local control panel. The unit belongs to the second generation of ctrlX hardware and is intended for compact, cabinet-mounted installations where high current density and network flexibility are priorities.
Continuous motor current is rated at 71 A while switching at 4 kHz, allowing the drive to sustain a substantial mechanical load without derating. For short acceleration bursts, it can supply a peak of 120 A at the same carrier frequency, giving machines reserve torque for indexing or pressing strokes. A nominal DC link of 750 V matches common rectifier sections and keeps semiconductor conduction losses low. Heat is removed by an internal air cooling path that circulates cabinet air through the heat sink fins, eliminating the need for external ductwork. Control electronics draw from a 24 V auxiliary supply that tolerates ±20% line variation, so logic remains active during brief mains dips. The housing carries a protection rating of IP20, which prevents finger contact with live parts and requires placement inside an electrical enclosure.
The housing has a frame width of 125 mm, a height of 309 mm, and a depth of 196.5 mm, keeping the footprint shallow for crowded cabinet lineups. The built-in Safe Torque Off channel disconnects gate signals from the output stage, providing a certified zero-torque state without external relays. Multi-Ethernet communication and a dedicated SERCOS III stack exchange status, diagnostic data, and motion commands with higher-level controllers. Startup energy is buffered by 1.7 mF of input capacitance, and inrush current is limited to 4 A for 20 ms before normal operation begins. Control power consumption can reach 105 W during operation. Motor terminations require field-selected connectors because a connector set is not included with the unit.
