The output for control circuit 2 is set additionally to
“
A2
”
to
“
A1
”
(regardless of the
programmed function for
|
A1
|
). Control circuit 1 has no output for the duration of the
switching.

Following restrictions apply for the control circuit 2:
•
The
“
Manual Mode
”
function in the
“
Setting
”
menu group only in
fl
uences control circuit 1!
•
The fuction Limit (see IO Setup
|
3D
|
and Controller Setup) in
fl
uences both control circuits simulta-
neously.
•
The
“
Max. Speed
”
setting by a digital input (see IO Setup
|
11D
|
) simultaneously in
fl
uences both
control circuits. I.e. at
“
1.Max. Speed
”
and at
“
2.Max. Speed
”
.
•
The controller con
fi
gurations (KP, KI, KD, TI see Controller Setup) are identical for both control
circuits. Fine adjustment is possible for each control circuit by the separate
“
Pband
”
setting.
