F2011, 02: FBS Vlv2 fail
Feedback of the NC and the NO
contact of safety valve 2 provided
the same potential after the de‐
bounce time has elapsed.
Check feedback signals P-0-1296 bit 2 and 3
Check the cable and plug-in connection of the feed‐
back signals of safety valve 1
Check feedback contacts of safety valve 2
If required, replace cable, connector or safety valve
F2011, 03: EN Vlv1 fail
If enable was granted (mode AF)
safety valve 1 has not opened with‐
in the debounce time.
Check control signal from HAT module (activation of
safety valves) of safety valve 1
Check cable and plug-in connection to safety valve 1
Test safety valve 1
If required, replace cable, connector, safety valve or
HAT module
F2011, 04: EN Vlv2 fail
If enable was granted (mode AF)
safety valve 2 has not opened with‐
in the debounce time.
Check control signal from HAT module (activation of
safety valves) of safety valve 2
Check cable and plug-in connection to safety valve 2
Test safety valve 2
If required, replace cable, connector, safety valve or
HAT module
F2011, 05: DA Vlv1 fail
If drive enable was not granted
(mode Ab) safety valve 1 has not
closed within the debounce time.
Check control signal from HAT module (activation of
safety valves) of safety valve 1
Check cable and plug-in connection to safety valve 1
Test safety valve 1
If required, replace cable, connector, safety valve or
HAT module
F2011, 06: DA Vlv2 fail
If drive enable was not present
(mode Ab), safety valve 2 has not
closed within the debounce time.
Check control signal from HAT module (activation of
safety valves) of safety valve 2
Check cable and plug-in connection to safety valve 2
Test safety valve 2
If required, replace cable, connector, safety valve or
HAT module
F2011, 07: test time Vlv1
The last test of safety valve 1 took
place too long ago. Operation with‐
out testing is not permitted.
Withdraw the control enable of the axis and re-grant it.
When the axis is stopped, safety valve 1 is tested.
F2011, 08: test time Vlv2
The last test of the safety valve 2
took place too long ago. Operation
without testing is not permitted.
Withdraw the control enable of the axis and re-grant it.
When the axis is stopped, safety valve 2 is tested.
F2017, error, category: Stop
1
F2017, D5025: actual veloci‐
ty exceeds valid range
Encoder jump monitoring has not
recognized valid position signals for
more cycles than specified in the
number of suppression cycles and
signals an encoder error.
Check encoder signals
If required, increase number of suppression cycles in
