3 SSI interface
The encoders provide an absolute signal of
a guided or free positioning element. The
sensor is contactlessly coupled with the po-
sitioning element via a stable inductive RLC
circuit.
In addition to the indication of process val-
ues via current and voltage outputs, the SSI
interface (Synchronous Serial Interface) has
become an established alternative in the
field of industrial automation. The process
value is transmitted either directly to the
higher-level controller (with SSI-card) or
to an appropriate fieldbus participant that
connects to all standard fieldbuses, such as
piconet®, BL67, BL20 or BLcompact.
The advantage of the SSI-interface is that
signals are directly and digitally transmitted
via the SSI telegram and are therefore more
precise and immune to interferences. Not
only process data is transmitted via SSI tel-
egram but also diagnostic bits.
Contactless encoders with SSI interface –
SSI interface Description
The fieldbus device is the master com-
manding a clock signal to which the sen-
sor responds synchronously via the SSI
telegram. The clock rate and the data
frame length are specified by the master.
Depending on the length of the connection
cable different clock rates are recommend-
ed (see section "Commissioning" on page
6). In order to adapt the clock rate to the
cable length, it is adjustable on the master
side. The data frame length and the process
value displayed as Gray or binary code must
be the same on the master and sensor side.
The encoder position can be captured in the
SSI synchronous as well as in asynchronous
mode. You can toggle between both modes
with a DIP switch (see section "Parametriza-
tion via teach function ", page 8). The asyn-
chronous mode is factory set. This makes
the SSI encoder compatible with virtually all
major SSI masters.

4 Commissioning
Sensor and SSI-master are linked with a con-
nection cable. In order to ensure proper data
traffic, it is recommended that you always
use shielded twisted-pair lines.
Make sure that the SSI-master and the sen-
sor have the same settings. The sensor's
type code contains the factory-set data
frame length of 25 bits as well as the Gray
code. The encoder adjusts itself automati-
cally to the specified master clock frequency
(62.5 kHz to 1 MHz).
In dependence on the transmission frequen-
cies, the following line lengths are recom-
mended:
Cable length Clock frequency
< 25 m < 1000 kHz
< 50 m < 500 kHz
< 100 m < 400 kHz
< 200 m < 200 kHz
< 400 m < 100 kHz
If the selected SSI-master doesn't provide
the request packets on time, operate the
sensor in the factory-set asynchronous
mode. This mode also works with an accu-
rately functioning master.
In time-critical applications, such as in the
control technology or motor commutation,
it is necessary that the encoder provides
extremely short and, in particular, constant
(synchronous) signal propagation times.
Here, the sensor must be operated in syn-
chronous mode together with a suitable
master. The sensor's sampling rate depends
on the master's SSI-cycle time, allowing syn-
chronous operation with SSI-cycle times of
700 Hz to 5 kHz. In synchronous mode, the
signal propagation delay is 200 µs, regard-
less of the cycle time. On selecting the SSI
master, note that a jitter of < 5 µs is required
in synchronous mode.
The nominal distance between positioning
element and sensor is 1.5 mm. Use the in-
cluded mounting aid MT-QR24 to adjust the
distance.
If positioning element and encoder are
mounted too far away from each other, the
signal will be weak. This status is indicated
by a steady yellow LED. If the distance be-
tween positioning element and encoder is
too large, i.e. RLC coupling is not given. This
status is indicated by a flashing yellow LED.
In addition, status bits within the SSI-process
data deliver diagnostic messages for proper
RLC coupling. If the encoder is moved dur-
ing a power cut, this is – after reconnecting
power – indicated by a red LED and a status
bit.
The encoder is factory set to a data frame
length of 25 bit. In this case, the singleturn
process data are found in bits 0 to 15 and
the multiturn process data in bits 16 to 21.
Bits 22 to 24 contain the diagnostic data.
You can apply further settings with the
software tool PACTware™, the TURCK pro-
gramming box USB-2-IOL-0002 (ident no.
6825482) and the associated adapter cable
RKC8.302T-1.5-RSC4T/TX320 (ident no.
6625003) as well as the IODD-file "IODD_
IOL_Ri-QR24.zip". (PACTware™ and IODD-file
can be downloaded from www.turck.com).
You can change the data frame length (24,
25 or 26 bit), the coding (Gray/binary) or the
distribution of the process data for example.
You can also disable the diagnostic data and
use the vacant bits for multiturn or single-
turn resolution instead. Only the singleturn
bits have to be set – the remaining bits in the
data packet are filled with the multiturn and
status bits accordingly (if these are enabled).

5 Mounting
Extensive range of mounting accesso-
ries (see section "Mounting accessories"
on page 11) for easy adaptation to many
different shaft diameters. Based on the
functional principle of oscillation circuit
coupling, the sensor operates absolutely
wear-free and is immune to magnetized
metal splinters and other interference
fields. Wrong installation is hardly possible.

8.3 Detailed list of adjustable parameters
Parameters Description
Multiturn reset In multiturn mode multiturn process data is stored in the encoder even after power loss. This means
that the device continues to count with the stored multiturn value after power recovery.
If the positioning element was relocated during a power loss, this is indicated by a status bit (mul-
titurn error ag) and a red LED.
This incident and the multiturn data are reset with this command.
SSI bit length 23, 24, 25, or 26 bit are parametrizable (factory setting "25 Bit")
SSI singleturn bit length 1) 10 to 18 bit are parametrizable.
Depending on the setting, the following assignments for singleturn process data are used:
bits 0 to 9 (10 bit), or bits 0 to 17 (18 bit). (factory setting "16 Bit“)
SSI Code (Gray/binary) 1) Bit coding (Gray, binary) parametrizable (factory setting "Gray")
SSI mode
(async/auto-sync/sync)
Parametrization of the encoder for operation with sync (deterministic) SSI-master (jitter < 5 µs) or
async SSI-master.
In sync mode the signal propagation time is optimal.
(Factory setting "Async")
SSI ags enabled 1) Bits 22, 23, 24 provide status information. These status bits can be disabled in this command. The va-
cated bits are used in this case for the multiturn process data. If 23 or 24 bit are parametrized under
SSI bit length, the SSI ags will automatically be disabled.
(Factory setting "SSI Flags On")
zero point Both singleturn as well as multiturn process data and the multiturn error ag will be reset.
Direction mode The direction can be parametrized from clockwise to counterclockwise as appropriate.
(Factory setting "CW Clockwise" in plan view on the positioning element)
factory setting 1) All parameters are reset to factory setting.
