Lifts and Elevators

Lifts and Elevators

Smooth, reliable and quiet operation combined with compact dimensions and product flexibility means that Control Techniques has become the drive of choice for modern lift systems. We integrate with almost any lift controller and can drive virtually any AC, DC or gearless motor. Optional software provides precision direct-to-floor operation for increased speed and comfort.

One AC Drive to Fit Your Motor Selection

Control Techniques have years of experience designing drives for elevators, and the result is the Unidrive SP AC Drive specially designed and rated to give optimum elevator performance. Unidrive SP is a thoroughbred drive for elevator applications. The smooth Vector control gives a high quality, low noise, jerk free ride.

Unidrive SP has a flexible integration policy that ensures it is open to all elevator controllers.

The drive accepts 12 different feedback devices including Incremental, SinCos, Endat, Hiperface encoders and Resolver
Temperature controlled ventilation fan speed for silent operation
High switching frequency (up to 16kHz) for quiet motor operation

Unidrive SP - taking you to another level

Program in familiar elevator units - quick start up with no complex calculations
Easy start with standstill autotune - faster commissioning as no shaft rotation required
High switching frequency - quiet motor for reduced building noise
Battery back-up operation as standard - makes emergency evacuation easy
Ideal for geared and gearless applications - less stock, faster learning, easier maintenance
Direct control of motor brake and contactor - reduced components, less wiring
Creep-to-floor or direct-to-floor positioning as standard - flexible, depending on your requirements
Active Thermal Management - tripless operation in high overload conditions
Secure Disable - reduces user cost in machine safety design

	CREEP to floor positioning
	DIRECT to floor positioning
	SHORT floor positioning

Simple to design into your emergency evacuation systems

DC battery supply can be connected for emergency evacuation on loss of mains power
Internal load measurement for automatic choice of direction

SM-Applications offers users real integration possibilities
The most powerful plug-in AC drive application module available to system designers. This module has built-in elevator profile generators for both geared and gearless systems. Parameters are in elevator industry units - mm, m/s, m/s2.
