A 15-pin Micro D-Sub male connector is positioned on the front of the FX3-MOCx for
connec
ting up to two encoders.
Important information
NOTICE
T
he screws of the Micro-D-Sub male connector are to be tightened alternately by one
turn until a torque of 0.2Nm is achieved.
NOTE
•
T
o make installation easier, we recommend using the connecting cables and
encoder/motor feedback connection boxes that are available as accessories (see
"Accessories for the safety controller", page 182).
•
The signals are assigned based on the type of encoder used (see "Connection of
encoders", page 92).
