Product details

18.5 kW normal duty, 15 kW heavy duty — which load class fits your motor

The ATV930D18N4 is a 380-480 V 3-phase variable speed drive from the Altivar Process ATV900 series, rated 18.5 kW for normal duty applications and 15.0 kW for heavy duty. The nominal output current is 39.2 A at 4 kHz carrier frequency for normal duty, derating to 31.7 A at 4 kHz for heavy duty — the heavy duty figure governs when the driven load demands 150% overload capability for 60 seconds, typical for conveyors, crushers, or extruders. The drive includes a braking chopper as standard, so dynamic braking with an external resistor is ready without an add-on module. The integrated EMC filter meets conducted emission limits for most industrial environments, with an optional EMC plate for higher attenuation.

Fieldbus fit and I/O expansion — what connects where

Communication ports include Modbus TCP, EtherNet/IP, and Modbus serial on the base unit. Three option slots (A, B, C) accept fieldbus modules for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (RJ45 or SUB-D 9 or screw terminals), or Ethernet Powerlink — the slot assignment follows the drive's option guide, so confirm the module order code against the slot letter. The control terminal block accepts 0.5-1.5 mm² (AWG 20-16) wire. The external supply for digital inputs is 24 V DC (19-30 V range), with an internal 24 V DC supply for digital inputs and STO (21-27 V). A 10.5 V DC reference supply drives a 1-10 kOhm potentiometer for speed reference.

Environmental limits and mounting constraints

The drive is rated IP21 with UL Type 1 enclosure — suitable for indoor, dry locations where dripping water is not present. Wall-mount orientation is vertical within ±10 degrees. Operating altitude is 1000-4800 m with a 1% current derating per 100 m above 1000 m. Ambient relative humidity range is 5-95% non-condensing per IEC 60068-2-3. Vibration resistance is 1.5 mm peak-to-peak at 2-13 Hz and 1 gn at 13-200 Hz per IEC 60068-2-6. Shock resistance is 15 gn for 11 ms per IEC 60068-2-27.

Standards compliance and lifecycle status

Total harmonic current distortion (THDI) is below 48% from 80-100% load per IEC 61000-3-12. The noise level is 59.5 dB — relevant for installation near personnel workstations.

Frequently asked questions

What is the ATV930D18N4 rated for in terms of motor power and output current?

The drive is rated 18.5 kW for normal duty and 15.0 kW for heavy duty, with a nominal output current of 39.2 A at 4 kHz carrier frequency (normal duty) and 31.7 A at 4 kHz (heavy duty). The supply voltage is 380-480 V 3-phase.

What fieldbus options can be added to the ATV930D18N4?

Option slot A accepts Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (RJ45, SUB-D 9, or screw terminals), and Ethernet Powerlink modules. Slots A, B, and C also accept digital/analog I/O extension modules, output relay extension modules, and encoder interface modules (digital 5/12 V, analog, or resolver).
