Encoders from Heidenhain for the elevator industry

Elevators must be safe and comfortable. Encoders from HEIDENHAIN, AMO, and RENCO make this possible. When installed on the main motor, brakes, shaft copying system, and doors, these encoders help the elevator car start gently, stop at just the right height, rapidly open and close its doors, and smoothly speed off again.

Ruggedness, reliability, and high resolution are key qualities of HEIDENHAIN rotary encoders. These characteristics make them proven and dependable motor control solutions on conventional traction elevators

For properly timed, jerkless braking, and exact positioning of the elevator car, its position in the shaft must be precisely measured and transmitted to the control. Absolute rotary encoders from HEIDENHAIN ensure the absolute position of the car is continuously available, even after a power outage, so the car can be moved straight to its destination.

Shorter elevator stopping times and higher transport volume can be attained if doors are opened and closed with speed and precision. The key to this is accurate and dynamic position measurement. HEIDENHAIN rotary encoders for door motors deliver the necessary rotational speed and position feedback in a highly compact design, with all models featuring an outside diameter smaller than 40 mm.

Easy implementation with EnDat

EnDat is the ideal interface for digital drive systems and position control loops using position encoder feedback. In particular, the interface’s purely serial design offers numerous benefits of great value to applications in the elevator industry. And implementation is made easier with the EnDat Master, or in the elevator industry, the EnDat Master Mini.

Designed specifically for fast and cost-effective implementation, it handles communication between the purely serial EnDat encoder and the higher-level application.
