NB!
If only two feedback signals are used, the feed-
back that is not to be used must be set to
No
Function
in par. 20-00, 20-03 or 20-06. Note that
each setpoint reference will be the sum of its re-
spective parameter value (20-21, 20-22 and
20-23) and any other references that are enabled
(see par. group 3-1*).
20-21 Setpoint 1
Range: Function:
0.000
*
[Ref
MIN
par.3-02 -
Ref
MAX
par. 3-03 UNIT
(from par. 20-12)]
Setpoint 1 is used in Closed Loop Mode to enter a setpoint ref-
erence that is used by the frequency converter’s PID Controller.
See the description of
Feedback Function
, par. 20-20.
NB!
Setpoint reference entered here is added to any
other references that are enabled (see par. group
3-1*).
20-22 Setpoint 2
Range: Function:
0.000
*
[Ref
MIN
- Ref
MAX
UNIT
(from par. 20-12)]
Setpoint 2 is used in Closed Loop Mode to enter a setpoint ref-
erence that may be used by the frequency converter’s PID
Controller. See the description of
Feedback Function
, par.
20-20.
NB!
The setpoint reference entered here is added to
any other references that are enabled (see par.
group 3-1*).
20-23 Setpoint 3
Range: Function:
0.000
*
[Ref
MIN
- Ref
MAX
UNIT
(from par. 20-12)]
Setpoint 3 is used in Closed Loop Mode to enter a setpoint ref-
erence that may be used by the frequency converter’s PID
Controller. See the description of par. 20-20 Feedback Function.
NB!
If the min and max references are altered, a new
PI - Autotune may be needed.
