Safety-related characteristic data for operation with non-safety-related
rotary encoder with mechanical fault exclusion
In accordance with EN 61800-5-2 : 2007, Table D.16 (Motion and position feedback sen-
sors), fault exclusions are permitted for faults in the mechanical connection between the
sensor (encoder) and motor.
Permitted encoder types and output signals
Permitted encoder types:
}
Rotary non-safety-related encoders
Permitted output signals:
}
Sin/Cos output signals 1Vss, reference voltage
}
Sin/Cos output signals 1Vss, differential
CAUTION!
The signal tracks Cos and Sin must be generated independently. This
means that the sine and cosine signals in the encoder must be conducted in
independent channels, from the optics to the interface.
The two signal tracks must not be generated by a common processor
One signal may not be derived from the other signal via an electronic circuit.
