Parameters 267
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
down 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
down 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. The drive does not trip if only reference is coming
from EFB and the communication is lost.
Changes to this parameter take effect after the control unit
is rebooted or the new settings validated by parameter
58.06 Communication control (Refresh settings).
See also parameters 58.15 Communication loss mode
and 58.16 Communication loss time.
Fault
No action No action taken (monitoring disabled). 0
Fault Drive trips on 6681 EFB comm loss. This occurs only if
control in the currently active control location is expected
from the EFB.
1
Last speed Drive generates an A7CE EFB comm loss warning and
freezes the speed to the level the drive was operating at.
The speed is determined on the basis of actual speed
using 850 ms low-pass filtering. This occurs only if control
is expected from the EFB.
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 occurs only 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 happens even
thought the drive is in a control location where the EFB
start/stop or reference is not used.
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 (Refresh settings).
See also parameters 58.14 Communication loss action
and 58.16 Communication loss time.
