116 BA8230
Zero zone additional demand
This demand forms part of a characteristics formation device on the additional
demand channel.
With unipolar demands it determines the range in which the analog demand read in
from terminal :29/:30 is limited to “Min. additional demand”.
With bipolar demands (-10 V ... +10 V) it defines the zero zone.
Adjustment range: 0 % ... 20 %
As supplied: 0.5 %
Main + additional demand
This parameter allows you to add an additional demand to the main (speed) demand.
As standard, the additional demand is the analog demand from terminal :29/:30.
Select list: - No
- :27/:28 + :29/:30
As supplied: No
4-20mA monitor
This parameter determines the response on detection of a wire break. The monitors
for the analog demands at terminals :27/:28 and :29/:30 are active if they were
selected as 4-20mA (line current) demand sources.
Select list: - Warning
- Shut down
As supplied: Shut down
Response:
- Warning:
Wire break detection generates a warning message in the event log. A signal can be
output to terminals :23/:24 through the selector switch “D-Output 1 :”23/:24”.
- Shut down:
If this is selected, a wire break causes the 8230 frequency inverter to be shut down
and creates a corresponding entry in the error log. The 8230 frequency inverter can
only be switched on again when the error is acknowledged.
