Description
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
depressed for over 3 seconds.
Number of transmitted 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.
Number of all received packets.
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.
Number of UART 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.
Number of CRC errors.
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 58.6 Communication

and 58.16 Communication loss
No action taken (monitoring disabled).
Drive trips on 6681 EFB communication
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
Drive generates an A7CE EFB comm loss
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
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.
