6.4 Changing the control source during operaon
The term "control sources" in this connecon refers to the digital signal sources from which
the inverter receives its start, stop, and reversal commands.
Possible control sources:
•
Digital inputs
•
Keypad
•
Network
Details
First, select in 0x2824 (P200.00) whether the start of the motor is to be congured exibly
(default seng) or exclusively via the keypad. 4Control selecon^ 54
If "Flexible I/O conguraon" is set, a change-over from one control source to another can be
eected during operaon via the funcons listed in the following table. The inverter not only
supports such a change-over via its digital inputs, but also as a funcon of internal inverter
states.

For precongured assignment of the digital inputs, see chapter "Func-
on assignment of the inputs and outputs (default seng)". ^ 48

Assignment of a trigger for the "Acvate keypad control" funcon.
Trigger = TRUE: acvate keypad as control source.

Assignment of a trigger for the "Acvate network control" funcon.
Trigger = TRUE: Acvate network control.
Trigger = FALSE: no acon / deacvate network control again.
0 Not connected No trigger assigned (trigger is constantly FALSE).
114 Network control acve (from version 02.00) TRUE if the network control is requested via bit 5 of the AC drive control
word 0x400B:001 (P592.01). Otherwise FALSE.
Notes:
•
Set this selecon if the network control is to be acvated via bit 5 of
the AC drive control word.
•
The AC drive control word can be used with any communicaon pro-
tocol.
