MultipleAxesPVTPulseOutputSet

Name
MultipleAxesPVTPulseOutputSet – Sets the configuration of pulse generation for
PVT trajectory.
Input tests
- Refer to section 7.1: "Input Tests Common to all XPS Functions".
- Checks group type (must be a MultipleAxes 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 PVT 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 PVT trajectory , error
( -22) is returned
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 output of pulses at constant time intervals on a PVT trajectory.
The pulses are generated between the first and the last trajectory elements. The
minimum possible time interval is CorrectorISRPeriod value (system.ref).
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
Example:
MultipleAxesPVTPulseOutputSet(Group1, 3, 5, 0.01)
One pulse will be generated every 10 ms between the start of the 3rd element and the
end of the 5th element.
