Drive selection memo: ATV930U30N4ZU
The ATV930U30N4ZU is a 3-phase variable speed drive from the Altivar Process ATV900 series, rated for 380–480 V supply. It delivers 3.0 kW in normal duty and 2.2 kW in heavy duty, with continuous output current of 7.2 A at 4 kHz (normal duty) or 5.6 A (heavy duty). The heavy duty rating is intended for constant torque loads such as conveyors or extruders; the normal duty rating covers variable torque applications like pumps and fans. The drive includes an integrated braking chopper as standard. The built-in EMC filter reduces external filtering requirements.
Communication and integration
Factory-installed communication ports support Modbus serial, EtherNet/IP, and Modbus TCP at configurable baud rates (9600, 19200, 4.8 kbps, 10/100 Mbits). Three option slots (A, B, C) accept fieldbus modules for Profibus DP, PROFINET, DeviceNet, EtherCAT, CANopen, and Ethernet Powerlink. Slot B also accommodates encoder/resolver feedback cards for closed-loop applications. Control wiring uses screw terminals rated for 0.5–1.5 mm² (AWG 20–16). Power wiring (line, motor, DC bus) accepts 2.5–6 mm² (AWG 14–10). Mounting is cabinet-mount with an IP21 / UL type 12 enclosure. Operating position is vertical ±10°.
Compliance documentation includes UL 508C (UL listing for industrial control equipment), IEC 61800-3 (EMC), IEC 61800-5-1 (safety), IEC 61000-3-12 (harmonic current emissions), IEC 60721-3 (environmental), IEC 61508 and ISO 13849-1 (functional safety). CE marked.
