What it is and what it does
The Siemens 6SL3320-1TH28-5AA0 is a SINAMICS Single Motor Module — a power stage for a single motor in a multi-axis drive system. It takes a 1035 V DC-link input and delivers 690 V three-phase AC output at 85 A, with internal air cooling. The module ships with the DRIVE-CLiQ cable, so it's ready to plug into the SINAMICS drive backbone for communication and control.
Integration notes
Mounts in a standard SINAMICS chassis or cabinet; the internal air cooling means it needs clearance for airflow — no external fan ducting required, but don't box it in tight. The DRIVE-CLiQ cable is included, so you're not hunting for a separate order code for the link to the Control Unit. Input is a fixed 1035 V DC-link bus; output is 690 V three-phase at 85 A — sized for a medium-horsepower motor on a 690 V line.
