Absolute Motorfeedback Series AD 34 - 1

TECHNICAL DATASHEET Absolute Motorfeedback Series AD 34 GENERAL INFORMATION For brushless servo motors Light duty encoder Unique mounting concept: Save installation time and cost Interfaces: SSI, BiSS-B or BiSS-C The AD34 is the most compact absolute encoder in class. It is available with a resolution up to 19 Bit Singleturn and 12 Bit Multiturn. The mechanical design consists of two ball bea- rings and a flexible torque support. The AD34 complements the ACURO-DRIVE series and is appropriate for use within BLDC servo motors with small frame sizes. The AD34 is available with a notched shaft, which saves installation time. Notched shaft saves installation cost Because of its innovative shaft mounting the AD34 saves work on the motor shaft. A com- mon 6 mm bore on the motor B - side is enough. AD34's notched shaft is inserted in the B side of the motor shaft in one process step. Fully digital control loop The new and completely digital OptoAsic technology enables the transition to a truly digital drive system. The conventional absolute encoders still have analog sine wave signals for the feedback of speed and position data. The AD34, however, provides fully digital position data up to 19 Bit per revolution over the BiSS interface with a variable clock rate up to 10 MHz. BiSS is the only open high speed bidirectional sensor interface available on the mar- ket. Backward compatibility to most of the existing drives is realized through the variant with SSI interface together with 2048 sine -cosine periods per revolution. Integrated diagnostic system The AD34 has an integrated diagnostic system that controls and regulates the internal si- gnals. Maximum motor uptime is achieved through the pre warning in case of any system error or aging effects well before they affect the function of the encoder. A code plausibility check guarantees that the output data represents always the true position. Also the opera- ting temperature can be measured and read out with 8 Bit resolution. If programmable limits are exceeded or under run this is indicated over warn and alarm bits. TECHNICAL DATA
