Motor sizing and overload capability
The 6SL3210-1KE32-4UF1: Rated 132.0 kW at 3AC 380-480 V, this drive handles constant-torque loads like conveyors and extruders at full nameplate. The 150% overload for 3 seconds gives headroom for breakaway torque on high-inertia starts or momentary load spikes — enough to clear a jam without tripping, but not a continuous duty cycle.
Fieldbus and I/O for controls integration
The I/O complement of 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output supports standalone speed control or distributed I/O for auxiliary functions like brake control or fault reset. Safe Torque Off (STO) is built in, meeting SIL 3 / PL e for safety circuits without an external safety relay on the motor branch. The STO function removes torque-producing power to the motor, so the drive cannot restart unintentionally during a safety demand.
Cabinet mounting and supply requirements
Frame size FSF measures 708 x 305 x 357 mm (H x W x D), which dictates the backpanel real estate and the gland plate layout for incoming power and motor cables. The drive requires an external 24 V control supply — the onboard power supply does not generate the 24 V bus. This is typical for SINAMICS G120C units; the 24 V powers the control electronics, I/O, and fieldbus interface, and must be present before the main power is applied for proper startup sequencing.
Unfiltered topology — plan for external EMC filtering
This variant is unfiltered, meaning there is no internal EMC filter on the input. The unfiltered design also means lower leakage current, which can be an advantage on IT (ungrounded) power systems or sensitive ground-fault protection schemes.
Lifecycle and compliance status
RoHS compliant since February 2017, with a REACH Article 33 notification for lead (CAS 7439-92-1) above 0.1% w/w in certain components. Export control classification is AL: N / ECCN: 9N9999, so no special license is required for standard industrial shipments.
