Siemens 6SL3120-2TE21-8AD0 is sinamics s120 double motor module. It converts the S120 DC link into two independently controlled 18 A motor outputs and exchanges drive data through DRIVE-CLiQ.
- Provides two 18 A motor channels
- Uses the booksize D mechanical format
- Applies optimized pulse patterns with internal air cooling
- Supports extended Safety Integrated functions
6SL3120-2TE21-8AD0 is installed with SINAMICS S120 600 V DC link, two compatible 400 V motors, CU320 or approved S120 control unit, supplied DRIVE-CLiQ cable and cooling path.
Engineered applications include Dual-axis machine control, Coordinated material-handling drives, Two-motor production cells, Safety-integrated axis modernization.
Important Notice: Discharge the S120 DC link, verify the booksize D mounting and airflow, record both motor and DRIVE-CLiQ assignments, then commission each channel separately before coordinated operation.
