ABB ACS880 PCP User Manual

Parameters 299
58.11 UART errors Displays a count of character errors received by the drive.
An increasing count indicates a configuration problem on
the bus.
Can be reset from the control panel by keeping Reset
depressed for over 3 seconds.
-
0…4294967295 Number of UART errors. 1 = 1
58.12 CRC errors Displays a count of packets with a CRC error received by
the drive. An increasing count indicates interference on the
bus.
Can be reset from the control panel by keeping Reset
depressed for over 3 seconds.
-
0…4294967295 Number of CRC errors. 1 = 1
58.14 Communication loss
action
Selects how the drive reacts to an EFB communication
break.
Changes to this parameter take effect after the control unit
is rebooted or the new settings validated by parameter
58.06 Communication control.
See also parameters 58.15 Communication loss mode and
58.16 Communication loss time.
Fault
No No action taken (monitoring disabled). 0
Fault Drive trips on 6681 EFB comm loss. This only occurs if
control is expected from the EFB (EFB selected as source
of start/stop in the currently active location).
1
Last speed Drive generates an A7CE EFB comm loss warning and
freezes the speed to the level the drive was operating at.
This only occurs if control is expected from the EFB.
The speed is determined on the basis of actual speed
using 850 ms low-pass filtering.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
2
Speed ref safe Drive generates an A7CE EFB comm loss warning and
sets the speed to the speed defined by parameter 22.41
Speed ref safe (or 28.41 Frequency ref safe when
frequency reference is being used). This only occurs if
control is expected from the EFB.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
3
Fault always Drive trips on 6681 EFB comm loss. This occurs even
though no control is expected from the EFB.
4
Warning Drive generates an A7CE EFB comm loss warning. This
occurs even though no control is expected from the EFB.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
5
58.15 Communication loss
mode
Defines which message types reset the timeout counter for
detecting an EFB communication loss.
Changes to this parameter take effect after the control unit
is rebooted or the new settings validated by parameter
58.06
Communication control.
See also parameters 58.14 Communication loss action
and 58.16 Communication loss time.
