Description
The ENA58IL series are high precision encoders
with internal magnetic sampling.
This multiturn absolute encoder transmits a position
value corresponding to the shaft setting via the SSI
interface (Synchronous Serial Interface).
The control module sends a start sequence to the
absolute encoder to obtain the position data. The
rotary encoder then sends the position data
synchronous to the cycles of the control module. It
is possible to select the counting direction with the
function input.

Absolute encoders ENA58IL-S***-SSI
Description
The Synchronous Serial Interface was specially developed for transferring the output data of an absolute encoder to a control device. 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 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 Tm has expired.
• No subsequent data transfer can be started until the data line switches to high again or the time for the clock pause Tp has expired.
• After the clock sequence is complete, the monoflop time Tm is triggered with the last falling pulse edge.
• The monoflop time Tm 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 possibility of detecting
transmission errors.
• In multiple transmission, n bits are transferred per data word in standard format. The value n equals the total resolution of the encoder.
As an example: a multiturn encoder with a resolution of 8192 steps/revolution (13 bit) and a max. number of 4096 revolutions (12 bit) has a total
resolution of n = 25 bit.
• If the clock change is not interrupted after the last falling pulse edge, ring slide operation automatically becomes active. This means that the information
that was stored at the time of the first clock change is generated again.
• After the first position transmission, the n+1 pulse controls data repetition. If the n+1 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.

In addition to the electrical preset function (PRESET 1) these models are equipped with 2 push buttons for manually setting the zero point of the rotary encoder.
Manually zero set
1. Simultaneously press and hold the push buttons A and B for 2 s.
After releasing the push buttons the rotary encoder sets the current position as zero point.
