Control Techniques and Leroy-Somer, both part of Emerson Industrial Automation, have introduced a new range of variable speed drives: E200 and E300, and a new permanent magnet motor, E27, designed for the elevator market.
The E200 and E300 drives and the E27 motor, make installing and commissioning elevator systems quick and simple. The drives have an intuitive user interface which allows easy adjustment via a backlit LCD keypad and rapid set-up in familiar elevator language and units. Meanwhile, the compact and silent E27 motor offers a completely new design to ease mechanical installation. A central sheave allows a simplification of the chassis, while also offering full access to the sheave and traction ropes.
Optimum ride comfort is provided by the new drive and motor solution: both E200 and E300 integrate a high resolution multi-step S-ramp for start, run, slowdown and stopping, as well as an ultra-fast current loop for vibration free motor control. Advanced brake control management means the drives have no rollback on starting without the need of a load-sensor. Additionally, the E300 drive offers extra levels of ride comfort with direct to floor positioning, an advanced communications interface supporting DCP3/4 and Modbus RTU protocols, short floor operations and a black box flight recorder. In association with the E27 motor equipped with optional load cell, ride comfort is improved as the starting torque is adapted depending on the load.
John Orrells, elevator market strategic manager for Emerson Industrial Automation, says: “The E200 and E300 drives, combined with the E27 motor, offer a complete solution for our elevator customers. The Emerson elevator solution takes speed and ease of setup and ride comfort to new heights. Our new products have been developed after extensive market research and feedback from our customers. Our research has directly influenced our engineering and design programme, resulting in drives and motors designed specifically to operate together. This is an additional guarantee of high performance for the customer, with simplified maintenance and after-sales service, while meeting the requirements of the elevator market.”
