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 Limit (
IO Setup
|
3D
|
and Controller Setup) function in
fl
uences both control circuits simulta-
neously.
•
The
“
Max. Speed
”
setting by a digital input (
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
Controller Setup) are identical for both control
circuits. Fine adjustment is possible for each control circuit by the separate
“
Pband
”
setting.

External Setpoint / External speed setting in manual operation
External setpoint setting or external manual operation are possible using a 0 - 10 V (0 - 20 mA, 4 - 20 mA) signal
at the
“

”
and
“
GND
”
terminals. Con

Information
Not possible in modes with 2 sensors and operation with a second control circuit because the second
analogue input is already occupied by it.
