The latest addition to the Hengstler ACURO-Drive absolute encoder series has been developed specifically for integration in 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, maintaining high precision throughout.
The absolute encoder features 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, it is suitable for incorporating in BLDC servo motors and such demanding applications 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.
The AD58DQ 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 with an integral encoder temperature sensor. In addition, the AD58DQ has 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.
