Central unit
Connector X7 - Differential analog inputs and touch probes
It is a 15-pin male connector of the SUB-D type used to connect the two touch probes and the analog
inputs.
Up to 4 differential analog inputs are allowed for supervision, monitoring, etc. The signal range may
be within ±5 V or ±10 V; the range is selected with PLC machine parameter “IANA5V (P130)”.
There are 4 probe inputs (two for 5V and two for 24V) and pin ·7· (0V probe input) must be connected
to the 0V of the external power supply.
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.
Connector X8 - Analog outputs.
It is a 15-pin female connector of the SUB-D type used for the analog command outputs
Each one of the outputs (O1 thru O8) correspond to the feedback inputs X1 thru X6. The name of
the axis connected to each one of them is determined by setting general parameters AXIS1 (P0)
thru AXIS8 (P7).
All shields must only be connected to ground at the CNC end leaving the other end free. The wires
of the shielded cable must not be longer than 75 mm without the protection shield.
