11.3 Setpoint change-over
Corresponding funcons make it possible to change over to other setpoint sources during
operaon.
Possible setpoint sources are:
•
Analog inputs
•
Keypad
•
Process input dat
a (network)
•
Parameterisable setpoints (preset values)
•
"Motor potenometer" funcon
Details
If no setpoint change-over funcon is acve, the standard setpoint sources are acve:
•
0x2860:001 (PAR 201/001): frequency setpoint sour
ce
•
0x2860:002 (PAR 201/002): process controller setpoint source
The setpoint source currently acve is shown in 0x282B:002 (PAR 125/002).
11.3.1 Priority of the setpoint sour
ces
Since only one setpoint source can be acve at a me, the following priories apply:
1.
Setpoint selecon via network c

Example of allocang priority
•
Digit
al input 4 is assigned to the "Setpoint sour
ce = keypad" funcon as trigger.
•
Digital input 5 1is assigned to the "Setpoint sour
ce = analog input 1" funcon as trigger.
Digital input 4 Digital input 5 Acve setpoint source
FALSE FALSE Standard setpoint source set in 0x2860:001 (PAR 201/001)
FALSE TRUE Analog input 1
TRUE FALSE Keypad
TRUE TRUE Keypad (since "Digital input 4" trigger has a higher priority than "Digital input 5" trigger)
11.3.2 Analog input setpoint source
The following funcons are used to select analog input 1 or analog input 2 as setpoint source.
Precondions
A setpoint change-over to the respecve analog input is only eected if no setpoint source
with a higher priority has been selected. 4Priority of the setpoint sources ^ 193
Parameter Name / value range / [default seng] Info
0x2631:014

Funcon assignment: Setpoint = AI1

Funcon list: Setpoint=AI1)
•
For possible sengs see descripon for
0x2631:001 (PAR 400/001). ^ 188
Assignment of a trigger for the "Setpoint = AI1" funcon.
Trigger = TRUE: analog input 1 is used as setpoint source (if the trigger
assigned has the highest setpoint priority).
Trigger = FALSE: no acon / deacvate funcon again.
4Analog input 1 ^ 211
00 Not connected No trigger assigned (trigger is constantly FALSE).
0x2631:015

Funcon assignment: Setpoint = AI2

Funcon list: Setpoint=AI2)
•
For possible sengs see descripon for
0x2631:001 (PAR 400/001). ^ 188
Assignment of a trigger for the "Setpoint = AI2" funcon.
Trigger = TRUE: analog input 2 is used as setpoint source (if the trigger
assigned has the highest setpoint priority).
Trigger = FALSE: no acon / deacvate funcon again.
4Analog input 2 ^ 213
00 Not connected No trigger assigned (trigger is constantly FALSE).
