Lenze i510 - Control Source Change-Over

11.1 Control source change-over
The term "control sources" in this connecon refers to the signal sources from which the
inverter receiv
es its start, stop, and reversal commands.
Possible control sources are:
•
Digital inputs
•
Process input data (network)
•
Keypad keys
Details
If exible control is set in 0x2824 (PAR 200), a change-over from one control source to another
can be eected during operaon using corresponding funcons. The inverter not only sup-
ports such a change-over via its digital inputs, but also as a funcon of internal inverter states.
In order to deacvate the digital inputs as control source and use the keypad or network as
control source instead:
•
By means of the "Keypad control" (0x2631:012 (PAR 400/012)) funcon, the keypad can be
acvated as control source. The drive can then be started and stopped via the
and
keypad keys.
•
The "Network enable" (0x2631:037 (PAR 400/037))
funcon serves to acvate the network
control mode. The inverter then responds to the start and stop commands received via net-
work.
Inverter behaviour when the control source is changed
If, during change-over of the control source, a funcon with a level-sensive trigger is acve
(e.g. Quick stop" or "DC braking"), the inverter responds to the new trigger state for the
respecve funcon immediately when the control source is changed over.
If a funcon with an edge-sensive trigger is acve instead (e.g. Forward start (CW)",
"Backward start (CCW)"), this funcon remains acve aer change-over unl another funcon
is acvated by the new control source.
If the keypad key is pressed, this state is saved internally. Restarng the drive
from another control sour
ce therefore requires pressing the
key rst in order
to cancel the stop c
ommand by the keypad again.

Control selecon
(Control source)
Selecon of the type of inverter control.
0 Terminal mode (exible I/O conguraon) This selecon enables a exible assignment of the start, stop, and rotat-
ing direcon commands with digital signal sources (e.g. digital inputs,
process data received via network).
1 Keypad This selecon enables starng and stopping of the inverter exclusively
via the start and stop key of the keypad.
•
Other signal sources for starng the inverter are ignored.
•
This selecon is advisable for an inial funconal test if no external
control sources are connected yet.
