Smart-Move Variable Frequency Drives

Power Electronics Smart-Move — Crane-Specific VFD for Bridge, Trolley, and Hoist Applications from 0.5 to 3HP 

Power Electronics Smart-Move is a compact crane-specific variable frequency drive engineered for bridge, trolley, and hoist motor control applications from 0.5 to 3HP — delivering smooth starting, smooth transitions, soft reversing, and integrated regeneration in a drive platform sized and priced for the light-duty crane and hoist applications where full-scale Micro-Speed CX or MX-Ultra drives represent unnecessary cost and complexity. Smart-Move is the Power Electronics specification for smaller crane and hoist motor control requirements where crane-specific performance — smooth acceleration, controlled deceleration, DC injection braking, and multi-speed control — is needed in a compact, straightforward package. 

Smart-Move delivers the core Power Electronics crane drive feature set in its compact form factor — soft starting that eliminates mechanical shock on drive train components during motor startup, smooth high-to-low and low-to-high speed transitions without the jerk and shock loading that across-the-line and basic contactor control produces, soft reversing for controlled direction changes, and DC injection braking for reliable motor stopping without friction brake dependency. Gang-Set six-second programming allows fast, straightforward drive commissioning without extensive parameter configuration — the same instant setup system used across the full Power Electronics Micro-Speed range. Smart-Move supports two and three position infinitely variable speed control and is available across standard three-phase voltages from 208V through 460VAC with an operating temperature range of -10°C to 50°C. 

Smart-Move is well suited to US jib crane, small monorail hoist, and light-duty bridge crane applications where motor horsepower requirements fall within the 0.5 to 3HP range and where the smooth starting, controlled transitions, and crane-specific braking performance of a dedicated crane drive deliver meaningful advantages over general-purpose soft-starts and basic contactor control systems. For applications above 3HP, the Micro-Speed CX or MX-Ultra is the appropriate Power Electronics specification.
