commands to encoder and setting of parameters
read out of position values
Multibyte commands* and parameters can be sent by asyn-
chronous protocol with parameterized baud rate.
The SSI interface can be used especially for real time signal
processing. It is possible to precisely scan the angle informa-
tion with the first negative clock.
The multibyte protocol consists of length byte, address byte,
command byte, data bytes and LRC byte.

Setting of parameters
It is always possible to set parameter over the SSI interface,
even if the encoder is in operation.
I/O description
V/R* Inputtosetdirectionofrotation.InputisnormallyHIGH.
V/R*-HIGH corresponds to increasing position values
while looking at flange and shaft rotation in clockwise
direction (CW). V/R*-LOW corresponds to increasing
positionvalueswhilelookingatflangeandshaftrotation
in counter- clockwise direction (CCW). Read-in of V/R*
voltage occurs during encoder power-on.
For example:
- SSI bit format (position resolution)
- direction of rotation CW/CCW
- monoflop time
- interface mode
ZERO Input to set position to zero. Input is normally LOW.
Zero setting procedure is initiated by a HIGH-pulse
(pulse length ≥ 100 ms). For maximum disturbance
immunity, connect input to 0 V.
- compensation of propagation time
- baud rate for parameter setting and programming
- signal code (binary, Gray)
DV* Output for error (data valid). Output is LOW-active, it
indicates an error with LOW-voltage.
Additional features:
- efficient error handling
- memory for operating time
- incremental totalisator (number of rotations)
- preset function
inputs and outputs
Control signals to V/R* and ZERO
Level HIGH > 0,8 * +Vs
Theresponseoncommands(data/„acknowledge“/„negative

reading the next position value.
Level LOW < 0,2 * +Vs
Connection V/R*-input with 15 kOhms against+Vs,
ZERO-input with 15 kOhms against 0 V
ReadingoutofpositionvaluesandprogrammableofDignalizer
is also possible via PCI-board.

Output signal from DV* and DVMT*
Connection DV*-output push-pull max. 30 mA
DVMT*-output push-pull max. 30mA
* With end shaft mounting, commands and parameter setting
by singlebyte protocol. Description on request.
