Frequently Asked Questions (FAQ)

1. Can I use the 6SL3210-1KE13-2UF2 with a single-phase supply?
No. This model requires a three-phase 380-480V supply. For single-phase operation, select a different G120C variant.

2. Does this drive include a braking resistor?
No. The Siemens 6SL3210-1KE13-2UF2 has DC link terminals for an external braking resistor. The resistor itself is sold separately.

3. How do I access the drive parameters without a panel?
Use the integrated web server via the PROFINET port. Alternatively, connect with STARTER or Startdrive software over Ethernet.

4. What is the difference between filtered and unfiltered versions?
Unfiltered drives like the 6SL3210-1KE13-2UF2 have no internal EMC filter. Add an external filter if needed for compliance.

5. Can I replace an existing G120 drive with this G120C model?
Check your power requirements carefully. The G120C series has different dimensions and I/O counts than standard G120 units. Verify mechanical fit first.
