3.2.94 Storage block (STORE2)
Purpose
Stores a setpoint angle signal which is generated from a speed signal. The storage process is
activated via the TP input X5/E4.

STORE2−PH2 ph − − − − − Outputs the next to last value saved by
X5/E5
STORE2−TP−INH d − − − − − HIGH = triggering via TP input E4 has been
effected. For further triggering, a positive
edge has to occur at the input
STORE1−ENTP.
Saving the angle signal
A speed signal at MCTRL−PHI−ACT 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 STORE2−ACT.
1. A LOW−HIGH edge at the TP input E4 saves the last angle signal and outputs it at
STORE2−PH1.
2. STORE2−ENTP = LOW−HIGH edge enables the TP input E4 for the next triggering process.
3. A new LOW−HIGH edge at the TP input E4 saves the last angle signal.
– STORE2−PH1 outputs this last angle signal.
– STORE2−PH2 outputs the next to last angle signal.
l STORE2−RESET = HIGH resets the memory and the integrators and enables the TP input E4
for the triggering process.
