What this module is and what it does
The Siemens 6SL3320-1TG32-6AA0 is a SINAMICS S120 Single Motor Module — a DC-fed inverter output stage that drives a single AC motor from a common DC bus. It accepts a 675 V to 1035 V DC input and delivers 500 V to 690 V three-phase AC at 260 A continuous, making it suited for medium-voltage motor loads in multi-axis drive systems where the DC link is shared across several axes.
Key ratings and what they mean for fit
The 260 A output rating is the continuous current at the motor terminals; it determines the maximum motor power the module can handle — roughly 300 kW at 690 V, though the exact motor rating depends on the duty cycle and ambient temperature. The 675-1035 V DC input range means this module connects to a DC bus supplied by a SINAMICS Smart Line Module or Active Line Module; it does not accept AC directly. The built-in internal air cooling requires clearance around the module for airflow — no external fan unit is needed, but the cabinet must have adequate ventilation.
Deployment context
This module is designed for built-in installation inside a control cabinet, typically on a mounting plate rather than a DIN rail. It includes the DRIVE-CLiQ cable for communication with the control unit (CU320-2 or similar), so no separate fieldbus wiring to the motor module is required — the control loop runs over the DRIVE-CLiQ ring.
