3.2.62.2 Storing STORE1 phase signal

A phase signal is created from a speed signal at STORE1−IN. The following sequence shows, in

addition to storing, the options of signal output

l The actual phase signal is output at STORE1−ACT.

1. A LOW−HIGH edge at the TP input E5 stores the last phase signal and outputs it at

STORE1−PH1.

2. STORE1−ENTP = LOW−HIGH edge enables the TP input E5 for the next triggering.

3. A renewed LOW−HIGH edge at the TP input E5 stores the last phase signal.

– STORE1−PH1 outputs this last phase signal.

– STORE1−PH2 outputs the last but one phase signal.

– STORE1−PHDIFF outputs the difference of STORE1−PH1 and STORE1−PH2.

l STORE1−RESET = HIGH resets memory, counter and integrators and activates the TP input

for triggering.

Output of the difference between both phase signals stored

l A two−stage counter controls the output to STORE1−PHDIFF.

l Every second triggering via the TP input results in a new output to STORE1−PHDIFF.

l STORE1−LOAD0 = HIGH resets the counter.

Additional control

1. STORE1−LOAD1 = LOW−HIGH edge, sets the counter to the first stage (preparation for the

output to STORE1−PHDIFF).

2. Triggering via TP input E5 sets the counter to the second stage (output to STORE1−PHDIFF is

done).

Tip!

If STORE1−LOAD1 is set cyclically, STORE1−PHDIFF outputs a new difference signal after every

triggering.

3.2.62.3 Storing STORE2 phase signal

A phase signal is created from a speed signal at MCTRL−PHI−ACT. The following sequence shows,

in addition to storing, the options of signal output.

l The actual phase signal is output to STORE2−ACT.

1. A LOW−HIGH edge at the TP input E4 stores the last phase signal and outputs it at

STORE2−PH1.

2. STORE2−ENTP = LOW−HIGH edge activates the TP input E4 for the next triggering.

3. A renewed LOW−HIGH edge at the TP input E4 stores the last phase signal.

– STORE2−PH1 outputs this last phase signal.

– STORE2−PH2 outputs the last but one phase signal.

l STORE2−RESET = HIGH resets the memory and integrator and activates the TP input E4 for

triggering.
