Description

This singleturn absolute encoder with modern fast technology transmits a position value correspon- ding to the shaft setting via the SSI interface (Syn- chronous Serial Interface). The resolution of the ASS58 is maximum 65536 steps per revolution. The devices of the ASS58 series are equipped with a microcontroller. The control module sends a clock bundle to the ab- solute encoder to obtain the position data. The ro- tary encoder then sends the position data synchronous to the cycles of the control module. It is possible to select the following items with func- tion inputs

  • the counting direction and
  • the zero-set function (preset value) The absolute encoder is mounted directly onto the application shaft, without any coupling. Rotation of the absolute encoder is prevented by a torque rest. The electrical connection is made by a 12-pin round plug connector. It is also possible to obtain a version with a 1 m cable connector.

The control module sends a clock bundle and the absolute encoder responds with the position value. Thus only 4 lines are required for the clock and data, no matter what the resolution of the rotary encoder is. The RS 422 interface is optically isolated from the power supply. SSI signal course Standard SSI output format Standard

  • At idle status signal lines "Data +" and "Clock +" are at high level (5 V).
  • The first time the clock signal switches from high to low, the data transfer in which the current information (position data ( Dn) and special bit (S)) is stored in the encoder is introduced.
  • The highest order bit (MSB) is applied to the serial data output of the encoder with the first rising pulse edge.
  • The next successive lower order bit is transferred with each following rising pulse edge.
  • After the lowest order bit (LSB) has been transferred the data line switches to low until the monoflop time T m has expired.
  • No subsequent data transfer can be started until the data line switches to high again or the time for the clock pause T p has expired.
  • After the clock sequence is complete, the monoflop time T m is triggered with the last falling pulse edge.
  • The monoflop time T m determines the lowest transmission frequency. SSI output format ring slide operation (multiple transmission)
  • In ring slide operation, multiple transmission of the same data word over the SSI interface makes it possible to offer the pos sibility of detecting trans- mission errors.
  • In multiple transmission, 25 bits are transferred per data word in standard format.
  • If the clock change is not interrupted after the last falling pulse edge, ring slide operation automatically becomes active. T his means that the infor- mation that was stored at the time of the first clock change is generated again.
  • After the first transmission, the 26 th pulse controls data repetition. If the 26th pulse follows after an amount of time greater than the monoflop time Tm, a new current data word will be transmitted with the following pulses. If the pulse line is exchanged, the data word is generated offset. Ring slide operation is possible up to max. 13 bits. Block diagram Line length The selection of the counting direction input (V/R) is activated with 0-level. The zero-set input (PRESET 1) is activated with 1-level.
