It's a spare part, meaning it drops into an existing SINAMICS drive cabinet where the original module failed or you need a matched replacement for a motor on that axis. Internal air cooling keeps it simple — no external plumbing, just panel airflow. The DRIVE-CLiQ cable ships with it, so you're not hunting for that proprietary link cable when the line is down. The 600 V DC input tells you this module sits on a DC link bus, not directly on the mains — it's part of a SINAMICS S120 or similar common-bus drive system. The 400 V three-phase output at 18 A is the motor-side rating; size it for a motor drawing up to that current in continuous duty. Internal air cooling means the panel builder needs to account for the module's own heat rejection — don't bury it in a sealed sub-panel without forced ventilation. The included DRIVE-CLiQ cable is a time-saver: one less part to order separately, and it guarantees the correct connector and pinout for the drive-to-module communication loop. ## Deployment context This module is designed for a SINAMICS drive cabinet — typically on a machine tool, conveyor line, or pump station where a common DC bus feeds multiple axes. It's not a standalone drive; it's the inverter stage that drives one motor from that shared DC link. The internal air cooling and DRIVE-CLiQ interface make it a straightforward swap for an existing slot in the rack, provided the panel has adequate airflow around the module.","metaTitle":"6SL3120-1TE21-8AA1 SINAMICS Single Motor Module, 18 A","metaDescription":"SINAMICS Single Motor Module 6SL3120-1TE21-8AA1. 600 V DC input, 400 V 3AC output, 18 A.
