Recall channels for internal command preset
Up to six corresponding inputs are provided for
channel recall of internal command presets. The
conjunction
options of the internal command channels may be
selectable via the parameter E21. The following op-
tions are
provided:
• priority dependent
• additive
At priority dependent channel recall the channel
with the lowest numerical designation has priority
against other
simultaneously adressed preset channels.
Example: Channels S1, S2, S3 are adressed.
Channel S1 has priority, the corre-
sponding internal command will be
assessed as input signal.
The preset channels have priority against the an-
alog signal input for the external command.
At additive channel recall the internal signal presets
of the recall channels as well as a possible signal
at the external signal input will be added. The sum
of the signal values is limited at 100%.
Example 1: Channel S1 = +50%, channel S2 = +20%,
external input signal = +5V (= +50%). The
sum is +120%, in this case +100% input
signal will be assessed.
Example 2: Channel S1 = +50%, channel S2 = +20%,
external input signal = -5V (= -50%). The
sum is +20%, in this case +20% input
signal will be assessed.
The preset channels are switched through during
the signal trigger at the dedicated inputs.
More details are shown from the technical
data.
The channel recall signals needs to be filte-
red as well as free of inductive surges and
modulations. To prevent malfunctions a high
signal quality is recommended.
