LOGIC CNC INPUTS AND OUTPUTS.
(REF: 1402)
Consulting signals for axes and spindles.
The CNC uses logic signals PARK and UNPARK to inform the PLC that the parking or
unparking processes are in execution.
To park an axis, the axis enable signals must be (=0). Likewise, after unparking the axis, the
axis enable signals must be set to (=1).
For safety, after parking and unparking an axis, the REFPOIN signal of the axis is set to (=0).
Maneuver to park an axis or spindle from the PLC.
1 From the PLC program, the PARKED mark is set to (=1) to park the relevant axis. The
CNC sets the PARK mark to (=1) and begins parking the axis.
For digital axes, the PLC must first remove the enable of the drive of the axis to be parked
(DRENA). Also, the CNC sends to the drive the command to park the axis.
2 The CNC considers the operation completed. It resets the PARK signal.
Maneuver to unpark an axis or spindle from the PLC.
3 From the PLC program, the PARKED mark is set to (=0) to unpark the relevant axis. The
CNC sets the UNPARK mark to (=1) and begins unparking the axis.
For digital axes, the CNC sends to the drive the command to unpark the axis.
4 The CNC considers the operation completed. It resets the UNPARK signal.
For digital axes, the PLC must activate the enable of the drive of the axis (DRENA).
ACTFBACK(axis)
The CNC uses this mark when the system has external+internal feedback. See machine
parameter FBACKSRC.
The CNC sets this mark high (=1) to indicate that the external feedback (direct feedback)
is being used . The CNC sets this mark high (=0) to indicate that the internal feedback (motor
feedback) is being used .
The feedback type may be swapped from the PLC using the mark FBACKSEL(axis). See
"FBACKSEL(axis)" on page 325.
In versions older than V2.00, at the end of the parking or unparking maneuver, the PLC must generate
a reset (RESETIN).

Example for parking and unparking an axis:
I10 = PARKEDV
Axis present. "V" axis presence sensor
NOT (PARKV OR UNPARKV OR PARKEDV) AND··· = DRENAV = SPENAV = SERVOVON
If the axis is neither parked nor being parked and the enabling conditions are met, the
axis gets enabled.
