Connectors X5, X6 - TTL and differential TTL feedback signals
They are 15-pin male connectors of the SUB-D type used for feedback system connections. They
admit differential (double-ended) and non-differential (single-ended) TTL feedback.
Each connector may be connected to up to 2 axes. General parameters AXIS5 (P4), AXIS6 (P5),
AXIS7 (P6) and AXIS8 (P7) must be set to let the CNC know which axis has been connected to
each one of them.
The cables must have overall shielding. The rest of the specifications depend on the feedback
system used and the cable length required.
The cable shield must be connected to the metallic hood at each end. The wires of the shielded cable
must not be longer than 75 mm without the protection shield.
It is highly recommended to run these cables as far as possible from the power cables of the machine.
Handwheel connection
When using a FAGOR 100P model handwheel, the axis selecting signal must be connected to the
reference mark (I0) pin of the corresponding axis 5 or 13 of this connector.
Protection at the connectors
It detects the error in axis pairs issuing the relevant error message.
"Supply voltage error on axis feedback *".
