Park/Unpark from the PLC.
This type of maneuver is good for applications that need manual parking of the axes either
while the machine is off or on (with or without power).
The axis parking/unparking maneuver, handled from the PLC program, is controlled using
the PARKED signal. This mark is usually affected by the input for the axis presence sensor.
The state of this signal is maintained even if the CNC is turned off.
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).
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.
