FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Where does the booksize format of 6SL3120-1TE21-8AA3 fit within a SINAMICS S120 line-up?
Confirm the complete MLFB, 600 VDC link design, booksize mechanical arrangement, 18 A motor requirement, control-unit topology, and approved SINAMICS project documentation.
Can another 18 A motor module directly replace 6SL3120-1TE21-8AA3?
No. Equal current does not prove compatibility; compare DC-link design, booksize format, pulse pattern, extended Safety Integrated scope, connectors, cooling, and project configuration.
What motor-side checks are required before energizing 6SL3120-1TE21-8AA3?
Verify the motor ratings, 400 V three-phase output wiring, shielding, grounding, DC-link condition, motor data, and approved drive configuration before enabling pulses.
Which cooling conditions apply to 6SL3120-1TE21-8AA3?
Maintain the specified internal-air-cooling path, booksize clearances, clean airflow, and approved cabinet ambient conditions; investigate restricted ventilation before attributing an overtemperature fault to the module.
Replacement of 6SL3120-1TE21-8AA3 affects extended Safety Integrated functions; what must be preserved?
Preserve the validated safety design and parameters, back up the project, verify the replacement hardware scope, and repeat the required safety validation before returning the axis to service.
Which commissioning records must be preserved before changing 6SL3120-1TE21-8AA3?
Save motor data, drive parameters, safety settings, DRIVE-CLiQ topology, fault history, DC-link information, and the verified SINAMICS project backup.
The documented scope for 6SL3120-1TE21-8AA3 includes a DRIVE-CLiQ cable; how should it be handled?
Confirm that the documented included cable is present, inspect its connectors and condition, and compare the required topology and routing with the installed SINAMICS S120 design.
