Input tests
- Refer to section 7.1: "Input Tests Common to all XPS Functions".
- Checks input parameter type: (-127)
- Checks Zygo is enabled: (-205)
Description
This function sets PEG (Position Event Generator) parameters.
The PEG function generates an electronic signal when the internal position
measurement meets criteria established by values programmed into the board by the
host system.
The first pulse is output when the position value enters the active region between the P1
and P2 values.
Additional pulses are output each time the position changes by the prescribed Delta
1, or in Delta 2 mode
For K1 number of PEG events, the increment value is Delta 1
For K2 number of PEG events, the increment value is Delta 2
This repeats K1, K2, K1, K2, etc...
Pulses stop when the position leaves the active region between the P1 and P2 values.
This may be repeated for travel in either direction between P1 and P2.
A number of other features, such as signal polarity, axis select (for 2402), and pulse
duration shall be programmable. Direction of motion is inferred by the position crossing
the start and stop values. Starting operation at a point in between the start and stop
values is undefined.
When entering at P1, the PEG starts with Delta 1. When entering at P2, the Delta is
selectable by the PEG P2 Delta bit in the PEG Control register (refer to PEG Control
register).
