5.4.8 Connection of encoders
The following encoder types can be connected to an FX3-MOCx:
•
A/
B incremental encoders HTL 24V, HTL 12V, TTL, max. 300kHz
•
A/B incremental encoder RS-422, max. 1MHz
6)
•
Sine-cosine encoder 1V
PP
, max. 120kHz
•
SSI encoder, RS-422, max. 1MBaud
WARNING
Ine
ffectiveness of the protective device due to selection of an unsuitable encoder
The target safety-related level may not be achieved in the event of non-compliance.
►
Select a suitable encoder.
►
Take suitable measures against the encoder’s systematic errors and common
causes of error.
Choosing the right encoder is crucial to achieving the desired safety integrity level
(SIL
) and performance level (PL). Systematic errors and common cause errors (CCF), in
particular, need to be minimized in this case.
More information on selecting the encoder and on measures against common fault
causes: see "Motion Control FX3-MOC0", page 34 and "Motion Control FX3-MOC1",
page 36.
NOTE
T
he wiring plan for the selected configuration of the encoder is a component of the
report for the configuration software.
►
Observe the selection options for the connection type of the encoder in the config‐
uration software.

We recommend using the connection cables and encoder/motor feedback con‐
nection boxes that are available as accessories (see "Accessories for the safety
controller", page 182).
