Arkel ARCUBE Monoblock Lift Control Unit

ARCUBE is Arkel’s monoblock lift control unit. The VVVF drive, the control board, the rescue function and the remaining electrical components sit in a single enclosure rather than in a conventional panel built up from separate parts.

Where it fits

ARCUBE is sized for ordinary residential and small commercial buildings: up to 16 stops, 1.75 m/s, duplex group control and four power classes from 4 kW (10 A) to 11 kW (26 A). Larger or faster installations move to ARCODE, which covers 64 stops, 4 m/s and groups of eight. ARMAXX is the option when the UPS and battery should live inside the unit as well.

Three versions

The base ARCUBE works with synchronous and asynchronous machines, in open or closed loop, with single- or double-button collective control. ARCUBE MRL and ARCUBE Slim MRL are specified for gearless machine room-less installations, run closed loop only, use down or full collective control, and add re-levelling and door pre-opening through integrated relays. ARCUBE Slim MRL measures 2,100 × 250 × 210 mm, which is what makes it fit beside a landing door frame.

Drive and safety

The motor drive is contactorless with an STO function, so the motor circuit is interrupted electronically instead of by power contactors. Rollback at start is prevented by pre-torque and anti-rollback functions. Car position comes from magnetic switches or from the motor encoder, and shaft wiring can be serial or parallel with ARCODE-compatible landing and car operating panels. Door bridging is available. The product is built to EN 81-20. Nazar Elevator supplies ARCUBE as a component and inside complete elevator systems.
