Overload profile and fault handling for mill duty
The ATV1200A106001010: Overload withstand is specified at 1.2 In for 60 s (standard overload) and 1.5 In for 3 s, with a high-overload tier at 1.5 In for 60 s and 1.85 In for 3 s — this drive handles sustained and transient overloads typical of rolling mill and crusher applications. Prospective line Isc is rated at 31.5 kA for 150 ms, so the drive can ride through a bolted fault on the incoming line without immediate damage, provided upstream protection coordinates within that window. Ground fault protection is integrated into the drive, and electrical isolation between power and control circuits is standard — both reduce nuisance trips and simplify troubleshooting in high-ambient, high-EMI environments.
Floor-standing build with forced convection cooling
The drive is assembled in a floor-standing enclosure with separate air flows for the power section and control compartment, a design that keeps heat from the 140000 m3/h cooling air volume away from the electronics. Forced convection cooling is standard. Operating position is vertical ±10 degrees; altitude derating begins at 1000 m (0.6 % per 100 m up to 2000 m). Pollution degree 2 per EN/IEC 61800-5-1 applies, so the enclosure is suitable for controlled indoor environments, not for heavy dust or conductive contamination.
Standards compliance and control interface
The drive carries CE marking and complies with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1 — covering electrical safety, EMC, and enclosure protection for industrial drive installations. Control wiring includes 4 software-configurable analogue inputs (0...20 mA / 4...20 mA, 250 Ohm impedance), 1 analogue output of the same type, and 6 discrete inputs (expandable to 10). The control supply is 220 V AC, 3 kVA, with an optional 220 V AC/DC external supply.
