and
.
No
No action taken (monitoring disabled).
0
Fault
Drive trips on
. 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
.
1
Last speed
Drive generates an
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
.
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
warning and sets
the speed to the speed defined by parameter
(or
when frequency reference
is being used). This only occurs if control is expected from the
EFB, or if supervision is forced using parameter
.
WARNING!
Make sure that it is safe to continue
operation in case of a communication break.
3
Fault always
. This occurs even though
no control is expected from the EFB.
4
Warning
Drive generates an
warning. This only
occurs if control is expected from the EFB, or if supervision is
forced using parameter
.
WARNING!
Make sure that it is safe to continue
operation in case of a communication break.
5
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
See also parameters
.

Any message addressed to the drive resets the timeout.
1
Cw / Ref1 / Ref2
