3 For Your Safety
The product is designed according to state-of-the-art technology. However, residual risks still
exist. Observe the following warnings and safety notices to prevent damage to persons and
property. Turck accepts no liability for damage caused by failure to observe these warning and
safety notices.
3.1 Intended use
These devices are designed solely for use in industrial areas.
Encoders with an SSI interface are used to measure angular movements. To do this, the devices
absorb mechanical rotary movements and convert them into electrical pulse sequences. Per re-
volution, a defined number of pulses is emitted.
The devices may only be used as described in these instructions. Any other use is not in
accordance with the intended use. Turck accepts no liability for any resulting damage.
3.2 Obvious misuse
nThe devices are not safety components and must not be used for personal or property
protection.
nAny use that exceeds the maximum permissible mechanical speed (see technical data) is
deemed to be not in accordance with the intended purpose.
3.3 General safety notes
nThe device only meets the EMC requirements for industrial areas and is not suitable for use
in residential areas.
nThe device may only be assembled, installed, operated, parameterized and maintained by
professionally-trained personnel.
nThe device may only be used in accordance with applicable national and international
regulations, standards and laws.
nIf safe operation is no longer guaranteed: Take the device out of operation and ensure that it
cannot be switched on again accidentally.

Product Description
Functions and operating modes
8Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
4 Product Description
The encoders in the REM… and RES… product series with SSI interface are available as solid
shaft or hollow shaft versions. The REM…E product series contains only solid shaft devices.
Devices are available in three different sizes, ranging from 36 to 100 mm.
The SSI encoders output the absolute angular position in RS485 format.
4.1 Device overview
Fig.1: Example – encoder with hollow shaft Fig.2: Example – encoder with solid shaft
4.2 Operating principle
Encoders detect rotational movements, such as the angle velocity of a shaft. Encoders convert
the rotational movements into electrical signals. The devices pass on the electrical signals to a
higher-level controller for evaluation. Encoders are designed as absolute and incremental
encoders with hollow or solid shafts.
Absolute encoders also supply the angle value after a startup if the value has changed when
deactivated. Incremental encoders only detect position changes when active by counting
periodic patterns. This normally involves the optical scanning of a rotating disk.
4.3 Functions and operating modes
4.3.1 Output function
The output signal of the encoders with SSI interface is based on the RS485 protocol with a
permissible load of max. ±20mA. The clock rate is 50kHz-2MHz.
If the clock cycle starts within the monoflop time, a second data transfer starts with the same
data. When the clock cycle starts after the monoflop time, the cycle starts with new values. The
update rate depends on the clock speed, the data length, and the monoflop time.
4.3.2 Input function
The encoder is provided with a SET input and a DIR input. The inputs can be set via a
HIGH signal. The response time of the inputs is 1ms.
The write cycles for the SET input are limited to 10,000.

NOTICE
Incorrect mounting
Risk of damage to the sensor
Do not modify or disassemble the encoder.
Do not make adjustments to the shaft after mounting.
Do not use a hammer to align the device.
Avoid impact loads.
Load the encoder shaft only within the permissible values (see technical data).
Do not rigidly connect the rotary encoder to shafts and flanges at the same time.
Use the coupling between the drive shaft and the encoder shaft or the hollow
shaft encoder flange.

6 Connection
The encoder is provided with an 8-pin M12 x 1 male connector with an SSI interface. Refer to
the sensor label or data sheet for the pin layout.
CAUTION
Connecting and disconnecting during operation
Device damage possible
Only connect the device when it is in a de-energized state.
Turck recommends the following cable lengths:
nFor asymmetrical transmission (no inverted signals): max. 10m
nFor symmetrical transmission (e.g. RS422 standard): max. 50m with twisted pairs
Connect all required cable cores as per the wiring diagram. Insulate the cable ends that
are not required to avoid short circuits.
Follow the operating instructions for the connecting cable used.
Disconnect the encoder from the connecting cable only when the encoder is de-ener-
gized.
Connect the shielding (if present) to the encoder housing.
The encoder and processor must always be switched on and off simultaneously.
Observe the operating voltage and maximum permissible output current (see technical
data).
EMC-compliant installation
Use shielded connection cables as control cables.
For symmetrical transmission (e.g. via RS422): Use twisted pair cables.
Connect protective earth to the rotary encoder and the evaluation unit (low impedance).
Route the connection cables separately from cables with high noise levels.
Do not connect devices with high noise levels to the encoder's power supply
(e.g. frequency converters, solenoid valves, or contactors), or ensure that suitable voltage
filtering is in place.

Troubleshooting
16 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
9 Troubleshooting
If the device does not function as expected, first check whether ambient interference is present.
If there is no ambient interference present, check the connections of the device for faults.
If there are no faults, there is a device malfunction. In this case, decommission the device and
replace it with a new device of the same type.
