Parameters 249
58.08 Received packets Displays a count of valid packets addressed to the drive.
During normal operation, this number increases constantly.
Can be reset from the control panel by keeping Reset down
for over 3 seconds.
-
0…4294967295 Number of received packets addressed to the drive. 1 = 1
58.09 Transmitted packets Displays a count of valid packets transmitted by the drive.
During normal operation, this number increases constantly.
Can be reset from the control panel by keeping Reset down
for over 3 seconds.
-
0…4294967295 Number of transmitted packets. 1 = 1
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 down
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 down
for over 3 seconds.
-

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 (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 The drive monitors communication loss when start/stop is
expected from the EFB on the currently active control
location.
The drive trips on 6681 EFB comm loss if control in the
currently active control location is expected from the EFB or
reference is coming from the EFB, and the communication is
lost.
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 if control or reference
is expected from the EFB.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
