Example (trgedge = 1...3):
An actuator with a closed loop stroke of 80µm is used as follows: rising edge (trgedge,1), start
point 10µm (trgss,10) end point (trgse,30) and interval 5µm (trgsi,5), i.e. trigger points are at 10,
15, 20, 25, 30µm. After reaching position 10µm (from a lower position; rising edge!) the trigger is
set and the next trigger point will be calculated (15µm), the trigger output will be reset after
n * 20µs (trglen,n) and the trigger function is waiting to reach the next trigger position (15µm) and
so on. After reaching the 30µm position, the next Trigger position is set to 10µm, the trigger
impulse will be generated when the 10µm position is reached from a lower position than 10µm
(rising edge).
Extended trigger functions (trgedge = 4 / 5 / 7):
The function trgedge,4 triggers at any change of moving direction, with trgedge,5 the output is
inverted to trgdge,4. No parameters will needed.
Abb: trgedge,4
Abb: trgedge,5
Function trgedge,7: at any change of moving direction a trigger with length n * 20µs appears
(parameter n: trglen).
Trigger function „moving trigger" (trgedge,6)
This function is parameterized by trgss, trgse, trgsi und trglen. On each period, only one trigger
appears, the trigger point "moves" at every period by its increment (trgsi). After reaching the end
position (trgse) the trigger point "moves" backward.
