XYZSplinePulseOutputSet

Name
XYZSplinePulseOutputSet – Sets the configuration of pulse generation of a Spline
trajectory.
Input tests
- Refer to section 7.1: "Input Tests Common to all XPS Functions".
- Checks group type (must be a XYZ group): (-8)
- Checks group name: (-19)
- Checks the pulse generation must not be in progress: (-22)
Description
This function configures and activates the pulse generation of a Spline trajectory. The
pulse generation is defined by a start element, an end element, and a time interval in
seconds. If a pulse generation is already activated on the selected Spline trajectory then
this function returns -22 ("Not allowed action") error.
Please note that the pulse output settings are automatically removed when the trajectory
is over. Hence, with the execution of every new trajectory, it is required to define the
pulse output settings again.
This capability allows to generate pulses at constant pulse trajectory curved length
intervals on a Spline trajectory. The pulses are generated between a pulse start trajectory
curved length and a pulse end trajectory curved length. All lengths are calculated in an
orthogonal XYZ coordination system.
The trajectory pulses are generated on the following GPIO ouputs:
GPIO ISA XPS
signals controller
Window GPIO2, pin 11
Pulses GPIO2, pin 12
To find the GPIO connector pin number from GPIOx.DOy, refer to XPS User's
Manual, Appendix / General I/O Description.
Example:
XYZSplinePulseOutputSet(Group1, 10, 30, 0.01)
One pulse will be generated every 10 μm on the Spline trajectory between 10 mm and
30 mm trajectory curved lengths.
Pulse start trajectory curved length = 10 mm
Pulse end trajectory curved length = 30 mm
Pulse trajectory curved length interval = 0.01 mm
