360 AxisLink Blocks
Virtual Axis Control
The Virtual Axis Control block enables and disables AxisLink virtual
axes. When you enable a virtual axis, you can use it as the master axis for
electronic gearing and position-lock cams, just as if it were another
physical master only axis. Only one of the two available virtual axes can
be enabled at the same time—enabling one virtual axis automatically
disables the other virtual axis.
The Virtual Axis Control block resides on the Advanced Motion Palette.
When a virtual axis is ON (enabled)
• AxisLink_status = 1
• Axis_status = 6
• Axis_fault = 0, if no faults are active on the axis
• Global_fault = 0, if no other faults are active on any axis
When a virtual axis is OFF (disabled)
• AxisLink_status = 0
• Axis_status = 12, if no faults are active on the axis
• Global_fault = 0, if no faults are active on any axis
The Axes System Variable AxisLink_failed indicates whether or not an
attempted AxisLink connection was successful. It has a value of 1 (true) if
an AxisLink virtual axis connection failed to be established (the axis
could not be found), and 0 (false) if not. When AxisLink_failed = 1,
Axis_fault = 6, Axis_status = 13, and Global_fault = 9.
Wait for Linked
You can select Wait for Linked only if you first specify the On state.
