XPS-Q8 Controller Motion Tutorial
Emergency Brake occurs when:
Case
Error
Standard end of run driver safety supervisor
Standard limit and home encoder safety supervisor
Standard limit and limit encoder safety supervisor
• Plus end of run is detected
• Minus end of run is detected
Line arc trajectory execution • Error occurs when reading or
getting trajectory parameters
• The user target position is
outside the
MinimumTargetPosition and
MaximumTargetPosition
value
• Actual positioner velocity is
greater than the
MaximumVelocity value
Spline trajectory execution
•
Error occurs when reading or
getting trajectory parameters
• The user target position is
outside the
MinimumTargetPosition and
MaximalTargetPosition value
• Actual positioner velocity is
greater than the
MaximumVelocity value
PVT trajectory execution • Error occurs when reading or
getting trajectory parameters
• Error occurs during trajectory
execution
• The user target position is
outside the
MinimumTargetPosition and
MaximalTargetPosition values
• Actual positioner velocity is
greater than the
MaximumVelocity value
S-gamma motion of a slave or a gantry
secondary positioner
•
Group positioner is not in the
gantry home process,
• And end of run detection is
enabled
• And the group is not a spindle
group
• And the user target position is
outside the
MinimumTargetPosition and
MaximalTargetPosition value
