New addition to absolute encoder series
2nd Quarter 2015
Other technologies
The newest addition to the Hengstler Acuro-Drive absolute encoder series has been developed specifically for integration into servo motors. The AD58DQ is designed for long-life operation in harsh environments where it is exposed to powerful vibrations, harsh shocks and high mechanical loads, but can also work with high precision in spite of these conditions.
It is an optical encoder with a multi-turn gear and optical scanning. The mechanical concept is based on a shaft assembly mounted in dual ball bearings with a flexible torque support. As a result, these encoders are suitable for incorporating in BLDC servo motors and demanding applications such as CNC, precision positioning and high resolution printing. The encoder is available with resolutions of up to 22 bits single-turn and 12 bits multi-turn.
It is equipped with the Drive-CLiQ interface of the Sinamics/Sinumeric drive family from Siemens. One of the most beneficial functions of the Drive-CLiQ is the simplified commissioning and automated configuration of components in the overall system.
Noise sensitive adaptor boxes and tedious configuration work are eliminated. There is a separate connection for a KTY motor winding temperature sensor, bringing the motor winding temperature directly into the encoder, where this data can be supplied to the system via the Drive-CLiQ. This guarantees reliable function and increased availability of the engine at high winding temperatures while eliminating the need to run two extra conductors. Another highlight of the AD58DQ is that it meets the requirements of SIL 2/ PL d/ Category 3 and safety integrated drive systems.
