338 Parameters
58.10 All packets Displays a count of valid packets addressed to any device on
the bus. During normal operation, this number increases
constantly.
Can be reset from the control panel by keeping Reset
depressed for over 3 seconds.
-
0…4294967295 Number of all received packets. 1 = 1
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.
