14.1 Control source change-over
The term "control sources" in this connecon refers to the digital signal sources from which
the inverter receives its start, stop, and reversal commands.
Possible control sources are:
•
Digital inputs
•
Keypad
•
Network
Details
First, select in 0x2824 (P200.00) whether the start of the motor is to be congured exibly
(default seng) or exclusively via the keypad. 4Control source selecon ^ 147
If "Flexible I/O conguraon" is set, a change-over from one control source to another can be
eected during operaon via the funcons listed in the following table. The inverter not only
supports such a change-over via its digital inputs, but also as a funcon of internal inverter
states.

For precongured assignment of the digital inputs, see chapter "Func-
on assignment of the inputs and outputs". ^ 82

For descripon of the basic funcons for controlling the motor, see
chapter "Start / stop motor". ^ 531
