TECHNICAL DATASHEET GENERAL INFORMATION For brushless servo motors Optical encoder with a true geared multiturn Interface: SSI, BiSS-B or BiSS-C Option Sinewave 1 Vpp: Harmonic distortion less than 1% The AD58 is an absolute encoder with a true geared Multiturn and optical sensing technolo- gy: The mechanical design consists of two ball bearings anda flexible torque support. The AD58 is ideally suited for integration into BLDC servo motors for demanding applications such as CNC precision machining and printing in professionell quality. Through its low cur- rent consumption the AD58 is contributing to lowering cost of ownership. 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 AD 58, however, provides fully digital position data up to 22 Bit (Singleturn) and 12 Bit (Multiturn) over the BiSS interface with a variable clock rate up to 10 MHz. This corresponds a singleturn resolution of morethan 4 million measured steps. TECHNICAL DATA
