4.7.4 Explanation of Axis Unit I/O
Individual spindle PLC signals connect to each Axis Unit via the PLC connector located on the
front of the Axis Unit.
CAUTION:
The PLC I/O wiring must be routed a minimum of 300 mm away from any
transient high voltage sources. Cable length must not exceed 50 feet.

Analog Output Disable Input (Normally Open)
This signal will disable the Analog output signals for the Axis Unit.
This allows all analog signals to be connected in parallel with only
one Unit's outputs enabled at a time.

Bank Data Output Signals (Normally Open)
These four (4) output signals designate various fastening conditions
and results as determined by Bank Select 0 & 1 (Pins 3 & 2) inputs.
Refer to 4.7.5 Axis Bank Select Table.

Spindle Bypass Input (Normal Open)
When active, all functions of this spindle are bypassed, and the
Bypass output is active. The Main Unit will ignore Bypassed
spindles. Judgment will be made on enabled spindles only.
SPINDLE BYPASS

PLC Output Disable Input (Normally Open)
When the Bank Outputs 0~3 are connected in parallel, this input
signal may be used to disable all but one unit at a time. For a
24 spindle system this would reduce the I/O requirements from
96 outputs, to 4 outputs and 24 inputs.

Bank Select Input Signals (Normally Open)
These two (2) inputs form a binary code that is used to define the
function/definition of outputs Bank Data 0~3 (Pins 1, 10, 9, & 8).
This allows up to 16 different output definitions with only four (4)
discrete outputs (4 Banks, 4 available outputs per Bank). Refer to
4.7.5 Axis Bank Select Table.
