FREQUENCY CONVERTERS

NX Inverter Datasheet - 17675 NX Series

A brake resistor can be incorporated in all drives below 72 A for a rapid machine deceleration without tripping.

SPECIFICATIONDATA

Integrated RFI filter – industrial level. Unsurpassed flexibility in communication via multiple concurrent fieldbuses. Very flexible I/O configuration. Multilingual control display. Multi Application software package pre-installed. Wide selection of additional application software available. NC1131-3 Engineering tool to write ‘bespoke’ applications. Versatile PC tools for loading, adjusting and comparing parameters. Parameter transfers between drives and applications. Slim, space-saving ‘bookshelf’ design.

GENERAL

Side-by-side installation. Super Cooling technology. The Honeywell NX Series drives have been built on the principles of Software and hardware modularity. The power unit utilises the most sophisticated semiconductor technology, with highly modular construction that can be adapted to a customer’s specific requirements. Typical power options include input and output filters, brake resistors together with IP21 (NEMA1) and IP54 (NEMA12) enclosure types. Two types of control units are available – the standard sensor-less vector control unit, which has performance that is usually sufficient for most applications. The closed loop vector control unit has servo type performance for more demanding applications – e.g. cranes, lifts, multiple synchronised drives. Integral RFI filter for 1
st environment, restricted distribution (household, light industry) as well as 2
nd environment (industry). Now available at 380…500 V, up to 110 kW (150 Hp).

SPECIFICATIONS

All drives are dimensioned using the same principle, i.e. the current required by the load. The selection of the drive is determined by the degree of overload capacity requires and the ambient temperature. Two types of overload conditions have been defines: Low overload – 10% for 1 minute every 10 minutes, 150% starting torque, 40°C ambient temperature. Typical applications include centrifugal fans and pumps as well as rotary compressors with slow variations in load. High overload – 50% for 1 minute every 10 minutes, 200% starting torque, 50°C ambient temperature. Typical applications include cranes, hoists, lifts and conveyors as well as others with rapidly changing loads. In addition to the rated currents for the low and high overloads, a two-second short-term overload current has been allowed.

FEATURES

Continuous runtime self-supervision and alarm system, for enhanced reliability and safety. Control logic can be powered from an external auxiliary supply, maintaining power to the control panel, internal drive functions and fieldbuses. Integrated AC choke for maximum protection and minimum harmonics. Each drive tested at maximum temperature and load prior to shipment.
