The ATV630C16N4US sits in the Altivar Process ATV600 family, a standard version drive for asynchronous and synchronous motors. It is rated 160 kW normal duty and 132 kW heavy duty at 380–480 VAC – the difference drives your sizing: use the normal duty figure for continuous pump/fan loads and the heavy duty figure when you need 150% overload for 60 seconds. The continuous output current is 302 A at 2.5 kHz (normal duty) and 250 A at 2.5 kHz (heavy duty), so the current rating already builds in the switching frequency derating. The integrated EMC filter meets IEC 61800-3 category C3 and is rated for 150 m of motor cable. That is enough to keep conducted emissions from the drive off your sensor lines if you maintain separation between the motor and control cable trays. If you see noise on a 4–20 mA loop near this drive, check the shield bond at the drive end before swapping the sensor – the filter is usually adequate up to that cable length. Safety function STO (safe torque off) with SIL3 capability is built in without an external module. That means you can wire the drive into a safety circuit without a separate safety relay, but verify the wiring matches the SIL3 logic: two independent paths for the STO request.
Duty profile comparison: normal vs heavy
The drive is rated 160 kW normal duty and 132 kW heavy duty. Line current at 480 V is 262 A for normal duty and 213 A for heavy duty.
Integration notes – mounting, cooling, wiring
Wall-mount only, IP00 (IP21 with an optional kit). Requires forced convection cooling with 600 m3/h airflow – leave clearance above and below the heatsink. Ambient relative humidity allowed 5–95% non-condensing. Vibration: 1.5 mm peak-to-peak at 2–13 Hz, 1 gn at 13–200 Hz. Shock: 15 gn for 11 ms. 8 discrete inputs, two configurable as pulse inputs up to 30 kHz. The base unit includes Modbus serial, Modbus TCP, and Ethernet IP; other fieldbus via option cards. The adjustable PID regulator is built in, so you can run closed-loop pressure or flow control without an external controller on simple loops.
