Hengstler AD37S Encoder, designed for a real single cable solution. The cores for the encoder’s signal transmission are integrated into the servo cable, which means that two cables are thereby combined to form a hybrid cable. This solution’s success is down to the benefits of space and weight optimization, and to the reasonable price and reduced connection technology. Basic requirement for the set-up of a single-cable solution between a servo motor and a servo controller is a digital encoder that is specifically developed for this type of communication.
The encoder is permanently connected to the servo motor. For this reason, the manufacturer of the servo motor needs to provide its customers with an end-to-end solution: Not only the servo motor needs to be equipped with a rotary encoder, the controller needs to be adapted to the concept of a single-cable solution as well - as communication is always established between two units. Hengstler offers special rotary encoders in its new product range that use the ACURO®link interface, an open protocol, creating the ideal symbiosis to meet the high requirements of single-cable solutions. “The ACURO®link interface was specifically designed to support two- and four-wire applications,”
