5.4.4 PLC/CNC connection cable: connector J1
Use a shielded cable with adequate wire cross section.
Ensure that the shielding braid of the above cable makes good contact with the metallic part of the 25
pin D-type connector.
The PLC/CNC connection cable must be less than 25 metres long.

DESCRIPTION
Arm Ready Output: informs the PLC/CNC that the

Machine Ready Output: informs the PLC/CNC that the machine is in the
MIDA TOOL EYE
ready condition:
Informs the PLC/CNC that there is not an alarm present on the E32A SSR.
Inhibit input: set to logic level 1 to disable touch signal processing, so that
the touch probe always appears as not deflected.
Probe Output: touch signal after being processed by E32A SSR when set
to sink/source hardware mode in function of JP1.
Probe Output: touch signal after being processed by E32A SSR (solid state
relay terminal a).
Probe Output: touch signal after being processed by E32A SSR (solid state
relay terminal b).
