3.2.93.1 Control via TP input X5/E5
The triggering signal STORE1−TP−INH indicates by means of a HIGH signal a triggering effected via
the TP input E5 (LOW−HIGH edge on X5/E5). At the same time STORE1−TP−INH signalises that the
triggering is deactivated and has to be reset to the active state. This can be effected via
l STORE1−RESET = HIGH
l STORE1−ENTP = LOW−HIGH edge
l STORE1−ENWIN = HIGH and the comparison of angle signals
Comparison of angle signals
The speed signal on STORE1−MASKI is integrated to a angle signal and is compared to the angle
signal on STORE1−MASKV.
If the condition | STORE1−MASKI |
w STORE1−MASKV
is met,
l the TP input E5 is enabled for the next triggering process with STORE1−ENWIN = HIGH,
l the integrator for the speed signal on STORE1−MASKI is reset.
3.2.93.2 Saving the angle signal
A speed signal at input STORE1−IN is integrated to a angle signal. In addition to the saving, the
following procedure shows the possibilities for the signal output.
l The current angle signal is output at STORE1−ACT.
1. A LOW−HIGH edge at the TP input E5 saves the last angle signal and outputs it at
STORE1−PH1.
2. STORE1−ENTP = LOW−HIGH edge enables the TP input E5 for the next triggering process.
3. A new LOW−HIGH edge at the TP input E5 saves the last angle signal.
– STORE1−PH1 outputs this last angle signal.
– STORE1−PH2 outputs the next to last angle signal.
– STORE1−PHDIFF outputs the difference of STORE1−PH1 and STORE1−PH2.
l STORE1−RESET = HIGH resets the memory, counters, and integrators and enables the TP
input E5 for the triggering process.
