Core Drive Specifications

NXI: NX Inverter Unit. It is designed to be fed by a shared, common DC bus arrangement rather than direct AC mains input.
0072: 72 Amps Nominal Current Rating.Low Overload (Pumps/Fans): Continuous maximum output of 72 A.
High Overload (Heavy Duty): Continuous maximum output of 61 A.
5: Mains Voltage Class. Rated for 380 V to 500 V AC grid systems (which corresponds to a DC bus voltage range of 465 V to 800 V DC).
A: Includes the Standard Alpha-numeric Control Keypad.
5: IP54 (NEMA 12) Enclosure Class. This offers strong, dust-protected, splash-resistant defense for hash operational environments.
T: Standard EMC Emission Level adhering to the IEC61800-3 specification for IT networks.
0: No integrated brake chopper.
C: Physical frame generation / module sizing designated as Frame FR7.
Internal Hardware & Control Boards (SVA1AF00000)

The suffix code segment details the exact internal logic, system software, and factory expansion board routing layout:

S: Air-cooled design system.
V: Internal coating option. It features varnished/coated circuit boards for moisture and corrosive air resilience.
Nsdpfx Aoy Ud Afekkolb
A: Standard Vacon System Interface architecture setup.
1AF00000: This sequence identifies the specific hardware configuration across the control expansion slots (A, B, C, D, and E):A1: OPT-A1 Basic I/O Board installed in Slot A. It provides 6 digital inputs, 1 digital output, 2 analog inputs, 1 analog output, +10V reference voltage, and a +24V auxiliary supply.
AF: OPT-AF Dual Relay Output Board installed in Slot B. It provides 2 programmable changeover relay outputs (NO/NC configuration).
00000: Slots C, D, and E are left empty from the factory, giving you expansion headroom for fieldbus communications (such as Profinet or EtherCAT) if needed
