No.
0 / uint32Displays 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.
All packets58.10
1 = 1 / 1 = 1Number of all received packets.0...4294967295
0 / uint32Displays 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.
UART errors58.11
1 = 1 / 1 = 1Number of UART errors.0...4294967295
0 / uint32Displays 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.
CRC errors58.12
1 = 1 / 1 = 1Number of CRC errors.0...4294967295
Fault / uint16Selects 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
58.6 Communication control.
See also parameters 58.15 Communication loss mode and
58.16 Communication loss time.

1
Drive trips on 6681 EFB communication loss. This only
occurs if control is expected from the EFB (EFB selected
as source of start/stop/reference in the currently active
control location), or if supervision is forced using parameter
58.36 EFB comm supervision force.
Fault
2
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, or if
supervision is forced using parameter 58.36 EFB comm
supervision force.
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.
