The 3ADT218587S0221: The 1200 A continuous rating governs the DC busbar sizing and upstream breaker coordination — this is a high-current drive section, not a modular block you drop onto a DIN rail. The 4Q (four-quadrant) designation means it regenerates into the line during overhauling loads; the DC-link must be tied to a braking resistor or a regenerative supply that can absorb the returned energy. Three analog inputs and two analog outputs are available for speed/torque reference and process feedback — typically 0-10 V or 4-20 mA, configurable in the drive parameter set. The 73 dB(A) sound level is audible in a control room; if the converter is in the same acoustic space as operators, ear protection zoning may be required.
Protection and environmental limits
Auxiliary terminals carry an IP00 rating per IEC 60529 and IEC 60947-1 — no enclosure protection at the wiring points, so the converter must be installed inside a panel or cabinet that provides the overall IP rating for the installation. The main power section's degree of protection depends on the cabinet design; the converter itself is a chassis-style unit meant for integration into a larger assembly.
